Subject: powerpc/fsl-booke: Fix InstructionTLBError execute permission check

In CONFIG_PTE_64BIT the PTE format has unique permission bits for user
and supervisor execute.  However on !CONFIG_PTE_64BIT we overload the
supervisor bit to imply user execute with _PAGE_USER set.  This allows
us to use the same permission check mask for user or supervisor code on
!CONFIG_PTE_64BIT.

However, on CONFIG_PTE_64BIT we map _PAGE_EXEC to _PAGE_BAP_UX so we
need a different permission mask based on the fault coming from a kernel
address or user space.

Without unique permission masks we see issues like the following with
modules:

Unable to handle kernel paging request for instruction fetch
Faulting instruction address: 0xf938d040
Oops: Kernel access of bad area, sig: 11 [#1]

Subject: powerpc/fsl-booke: Move loadcam_entry back to asm code to fix SMP
 ftrace

When we build with ftrace enabled its possible that loadcam_entry would
have used the stack pointer (even though the code doesn't need it).  We
call loadcam_entry in __secondary_start before the stack is setup.  To
ensure that loadcam_entry doesn't use the stack pointer the easiest
solution is to just have it in asm code.

pcibios_fixup_device_resources() presently skips over resources flagged
with IORESOURCE_PCI_FIXED, which is a remnant of the old PCI-auto code.
The only user for this at present is the Dreamast GAPSPCI code which
can't tolerate any adjustments to the BARs, but a combination of the
IORESOURCE_PCI_FIXED and zeroed out hose offsets does the right thing for
this case already, so we simply kill off the special casing.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With no word size given in the users platform data, a generic spi host
controller driver will assume a default word size of eight bit. This
causes transmission to be performed bytewise, which will fail on little
endian machines for sure. Failure on big endian depends on usage
of slave select to mark word boundaries.

Anyway, ad7877 is specified to work with 16 bit per word, so
unconditionally set the word size accordingly. Flag an error where 16
bit per word is not available.

Subject: sched: Fix PROVE_RCU vs cpu_cgroup

PROVE_RCU has a few issues with the cpu_cgroup because the scheduler
typically holds rq->lock around the css rcu derefs but the generic
cgroup code doesn't (and can't) know about that lock.

Provide means to add extra checks to the css dereference and use that
in the scheduler to annotate its users.

The addition of rq->lock to these checks is correct because the
cgroup_subsys::attach() method takes the rq->lock for each task it
moves, therefore by holding that lock, we ensure the task is pinned to
the current cgroup and the RCU derefence is valid.

That leaves one genuine race in __sched_setscheduler() where we used
task_group() without holding any of the required locks and thus raced
with the cgroup code. Solve this by moving the check under the
appropriate lock.

Subject: ipvs: Add missing locking during connection table hashing and
 unhashing

The code that hashes and unhashes connections from the connection table
is missing locking of the connection being modified, which opens up a
race condition and results in memory corruption when this race condition
is hit.

Here is what happens in pretty verbose form:

CPU 0					CPU 1
------------				------------
An active connection is terminated and
we schedule ip_vs_conn_expire() on this
CPU to expire this connection.

					IRQ assignment is changed to this CPU,
					but the expire timer stays scheduled on
					the other CPU.

					New connection from same ip:port comes
					in right before the timer expires, we
					find the inactive connection in our
					connection table and get a reference to
					it. We proper lock the connection in
					tcp_state_transition() and read the
					connection flags in set_tcp_state().

ip_vs_conn_expire() gets called, we
unhash the connection from our
connection table and remove the hashed
flag in ip_vs_conn_unhash(), without
proper locking!

					While still holding proper locks we
					write the connection flags in
					set_tcp_state() and this sets the hashed
					flag again.

ip_vs_conn_expire() fails to expire the
connection, because the other CPU has
incremented the reference count. We try
to re-insert the connection into our
connection table, but this fails in
ip_vs_conn_hash(), because the hashed
flag has been set by the other CPU. We
re-schedule execution of
ip_vs_conn_expire(). Now this connection
has the hashed flag set, but isn't
actually hashed in our connection table
and has a dangling list_head.

					We drop the reference we held on the
					connection and schedule the expire timer
					for timeouting the connection on this
					CPU. Further packets won't be able to
					find this connection in our connection
					table.

					ip_vs_conn_expire() gets called again,
					we think it's already hashed, but the
					list_head is dangling and while removing
					the connection from our connection table
					we write to the memory location where
					this list_head points to.

The result will probably be a kernel oops at some other point in time.

This race condition is pretty subtle, but it can be triggered remotely.
It needs the IRQ assignment change or another circumstance where packets
coming from the same ip:port for the same service are being processed on
different CPUs. And it involves hitting the exact time at which
ip_vs_conn_expire() gets called. It can be avoided by making sure that
all packets from one connection are always processed on the same CPU and
can be made harder to exploit by changing the connection timeouts to
some custom values.

Subject: genirq: Deal with desc->set_type() changing desc->chip

The set_type() function can change the chip implementation when the
trigger mode changes. That might result in using an non-initialized
irq chip when called from __setup_irq() or when called via
set_irq_type() on an already enabled irq.

The set_irq_type() function should not be called on an enabled irq,
but because we forgot to put a check into it, we have a bunch of users
which grew the habit of doing that and it never blew up as the
function is serialized via desc->lock against all users of desc->chip
and they never hit the non-initialized irq chip issue.

The easy fix for the __setup_irq() issue would be to move the
irq_chip_set_defaults(desc->chip) call after the trigger setting to
make sure that a chip change is covered.

But as we have already users, which do the type setting after
request_irq(), the safe fix for now is to call irq_chip_set_defaults()
from __irq_set_trigger() when desc->set_type() changed the irq chip.

It needs a deeper analysis whether we should refuse to change the chip
on an already enabled irq, but that'd be a large scale change to fix
all the existing users. So that's neither stable nor 2.6.35 material.

Subject: x86, irq: Rename gsi_end gsi_top, and fix off by one errors

When I introduced the global variable gsi_end I thought gsi_end on
io_apics was one past the end of the gsi range for the io_apic.  After
it was pointed out the the range on io_apics was inclusive I changed
my global variable to match.  That was a big mistake.  Inclusive
semantics without a range start cannot describe the case when no gsi's
are allocated.  Describing the case where no gsi's are allocated is
important in sfi.c and mpparse.c so that we can assign gsi numbers
instead of blindly copying the gsi assignments the BIOS has done as we
do in the acpi case.

To keep from getting the global variable confused with the gsi range
end rename it gsi_top.

To allow describing the case where no gsi's are allocated have gsi_top
be one place the highest gsi number seen in the system.

This fixes an off by one bug in sfi.c:

Subject: ACPI: Do not try to set up acpi processor stuff on cores exceeding
 maxcpus=

Patch is against latest Linus master branch and is expected to be
safe bug fix.

You get:
ACPI: HARDWARE addr space,NOT supported yet
for each ACPI defined CPU which status is active, but exceeds
maxcpus= count.

As these "not booted" CPUs do not run an idle routine
and echo X >/proc/acpi/processor/*/throttling did not work
I couldn't find a way to really access not onlined/booted
machines. Still this should get fixed and
/proc/acpi/processor/X dirs of cores exceeding maxcpus
should not show up.

I wonder whether this could get cleaned up by truncating possible cpu mask
and nr_cpu_ids to setup_max_cpus early some day
(and not exporting setup_max_cpus anymore then).
But this needs touching of a lot other places...

Subject: perf record: Don't call newt functions when not initialized
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When processing events we want to give visual feedback to the user when
using the newt browser, so there are ui_progress calls in
__perf_session__process_events, but those should check if newt is being
used.

Based on Intel Vol3b (March 2010), the event
SNOOPQ_REQUEST_OUTSTANDING is restricted to counters 0,1 so
update the event table for Intel Westmere accordingly.

Subject: ACPI: Store NVS state even when entering suspend to RAM

https://bugzilla.kernel.org/show_bug.cgi?id=13931 describes a bug where
a system fails to successfully resume after the second suspend. Maxim
Levitsky discovered that this could be rectified by forcibly saving
and restoring the ACPI non-volatile state. The spec indicates that this
is only required for S4, but testing the behaviour of Windows by adding
an ACPI NVS region to qemu's e820 map and registering a custom memory
read/write handler reveals that it's saved and restored even over suspend
to RAM. We should mimic that behaviour to avoid other broken platforms.

Note that this change is a workaround, not a permanent fix.
For the permanent fix is to figure out what compatibility
means and to actually be compatible...

Subject: perf/tracing: Fix regression of perf losing kprobe events

With the addition of the code to shrink the kernel tracepoint
infrastructure, we lost kprobes being traced by perf. The reason
is that I tested if the "tp_event->class->perf_probe" existed before
enabling it. This prevents "ftrace only" events (like the function
trace events) from being enabled by perf.

Unfortunately, kprobe events do not use perf_probe. This causes
kprobes to be missed by perf. To fix this, we add the test to
see if "tp_event->class->reg" exists as well as perf_probe.

Normal trace events have only "perf_probe" but no "reg" function,
and kprobes and syscalls have the "reg" but no "perf_probe".
The ftrace unique events do not have either, so this is a valid
test. If a kprobe or syscall is not to be probed by perf, the
"reg" function is called anyway, and will return a failure and
prevent perf from probing it.

Subject: ALSA: usb-audio: parse UAC2 sample rate ranges correctly

A device may report its supported sample rates in ranges rather than in
discrete triplets. The code used to only parse the MIN field instead of
properly paying attention to the MAX and RES values.

Also, handle RES values of 1 correctly and announce a continous sample
rate range in this case.

Subject: ALSA: usb-audio: fix UAC2 control value queries

For RANGE requests, we should only query as much bytes as we're in fact
interested in.

For CUR requests, we shouldn't confuse the firmware with an overlong
request but just ask for 2 bytes.

This might need fixing in the future as it's not entirely clear when to
dispatch 1-byte, 2-byte and 4-byte request blocks. For now, we assume
everything is coded in 16bit - this works for all firmware
implementations I've seen.

It just hit me.
It's the offset calculation in reloc_location() which overflows:
        return (void *)elf->hdr + sechdrs[section].sh_offset +
               (r->r_offset - sechdrs[section].sh_addr);

E.g. for the first rodata r entry:
r->r_offset < sechdrs[section].sh_addr
and the expression in the parenthesis produces 0xFFFFFFE0 or something
equally wise.

Subject: ACPI / ACPICA: Do not attempt to disable GPE when installing handler

Commit 0f849d2cc6863c7874889ea60a871fb71399dd3f (ACPICA: Minimize
the differences between linux GPE code and ACPICA code base)
introduced a change attempting to disable a GPE before installing
a handler for it in acpi_install_gpe_handler() which was incorrect.
First, the GPE disabled by it is never enabled again (except during
resume) which leads to battery insert/remove events not being
reported on the Maxim Levitsky's machine.  Second, the disabled
GPE is still reported as enabled by the sysfs interface that only
checks its enable register's enable_for_run mask.

Revert this change for now, because it causes more damage to happen
than the bug it was supposed to fix.

Subject: ACPI / ACPICA: Use helper function for computing GPE masks

In quite a few places ACPICA needs to compute a GPE enable mask with
only one bit, corresponding to a given GPE, set.  Currently, that
computation is always open coded which leads to unnecessary code
duplication.  Fix this by introducing a helper function for computing
one-bit GPE enable masks and using it where appropriate.

Subject: cifs: don't attempt busy-file rename unless it's in same directory

Busy-file renames don't actually work across directories, so we need
to limit this code to renames within the same dir.

This fixes the bug detailed here:

Subject: cifs: implement drop_inode superblock op

The standard behavior for drop_inode is to delete the inode when the
last reference to it is put and the nlink count goes to 0. This helps
keep inodes that are still considered "not deleted" in cache as long as
possible even when there aren't dentries attached to them.

When server inode numbers are disabled, it's not possible for cifs_iget
to ever match an existing inode (since inode numbers are generated via
iunique). In this situation, cifs can keep a lot of inodes in cache that
will never be used again.

Implement a drop_inode routine that deletes the inode if server inode
numbers are disabled on the mount. This helps keep the cifs inode
caches down to a more manageable size when server inode numbers are
disabled.

Subject: ACPI / ACPICA: Fix low-level GPE manipulation code

ACPICA uses acpi_ev_enable_gpe() for enabling GPEs at the low level,
which is incorrect, because this function only enables the GPE if the
corresponding bit in its enable register's enable_for_run mask is set.
This causes acpi_set_gpe() to work incorrectly if used for enabling
GPEs that were not previously enabled with acpi_enable_gpe().  As a
result, among other things, wakeup-only GPEs are never enabled by
acpi_enable_wakeup_device(), so the devices that use them are unable
to wake up the system.

To fix this issue remove acpi_ev_enable_gpe() and its counterpart
acpi_ev_disable_gpe() and replace acpi_hw_low_disable_gpe() with
acpi_hw_low_set_gpe() that will be used instead to manipulate GPE
enable bits at the low level.  Make the users of acpi_ev_enable_gpe()
and acpi_ev_disable_gpe() call acpi_hw_low_set_gpe() instead and
make sure that GPE enable masks are only updated by acpi_enable_gpe()
and acpi_disable_gpe() when GPE reference counters change from 0
to 1 and from 1 to 0, respectively.

Subject: ACPI / ACPICA: Avoid writing full enable masks to GPE registers

ACPICA uses acpi_hw_write_gpe_enable_reg() to re-enable a GPE after
an event signaled by it has been handled.  However, this function
writes the entire GPE enable mask to the GPE's enable register which
may not be correct.  Namely, if one of the other GPEs in the same
register was previously enabled by acpi_enable_gpe() and subsequently
disabled using acpi_set_gpe(), acpi_hw_write_gpe_enable_reg() will
re-enable it along with the target GPE.

To fix this issue rework acpi_hw_write_gpe_enable_reg() so that it
calls acpi_hw_low_set_gpe() with a special action value,
ACPI_GPE_COND_ENABLE, that will make it only enable the GPE if the
corresponding bit in its register's enable_for_run mask is set.

Subject: ACPI / ACPICA: Fix GPE initialization

While developing the GPE reference counting code we overlooked the
fact that acpi_ev_update_gpes() could have enabled GPEs before
acpi_ev_initialize_gpe_block() was called.  As a result, some GPEs
are enabled twice during the initialization.

To fix this issue avoid calling acpi_enable_gpe() from
acpi_ev_initialize_gpe_block() for the GPEs that have nonzero
runtime reference counters.

Subject: ACPI / ACPICA: Fix sysfs GPE interface

The sysfs interface allowing user space to disable/enable GPEs
doesn't work correctly, because a GPE disabled this way will be
re-enabled shortly by acpi_ev_asynch_enable_gpe() if it was
previosuly enabled by acpi_enable_gpe() (in which case the
corresponding bit in its enable register's enable_for_run mask is
set).

To address this issue make the sysfs GPE interface use
acpi_enable_gpe() and acpi_disable_gpe() instead of acpi_set_gpe()
so that GPE reference counters are modified by it along with the
values of GPE enable registers.

Some bogus firmwares include properties with "/" in their name. This

We don't care about those properties, and we don't want to encourage

Subject: ixgbe: fix for race with 8259(8|9) during shutdown

There is a small window where the watchdog could be running as the
interface is brought down on a NIC with two ports wired back to back.
If ixgbe_update_status is then called can lead to a panic.  This patch
allows the update to bail if we are in that condition.

This issue was orignally reported and fix proposed by Akihiko Saitou.

Subject: e1000: Fix message logging defect

commit 675ad47375c76a7c3be4ace9554d92cd55518ced
removed the capability to use ethtool.set_msglevel to
control the types of messages emitted by the driver.

That commit should probably be reverted.

If not, then this patch fixes a message logging defect
introduced by converting a printk without KERN_<level>
to e_info.

This also reduces text by about 200 bytes.

Subject: ixgbe: fix automatic LRO/RSC settings for low latency

This patch added to 2.6.34:

	commit f8d1dcaf88bddc7f282722ec1fdddbcb06a72f18
	Author: Jesse Brandeburg <jesse.brandeburg@intel.com>
	Date:   Tue Apr 27 01:37:20 2010 +0000

	    ixgbe: enable extremely low latency

introduced a feature where LRO (called RSC on the hardware) was disabled
automatically when setting rx-usecs to 0 via ethtool.  Some might not
like the fact that LRO was disabled automatically, but I'm fine with
that.  What I don't like is that LRO/RSC is automatically enabled when
rx-usecs is set >0 via ethtool.

This would certainly be a problem if the device was used for forwarding
and it was determined that the low latency wasn't needed after the
device was already forwarding.  I played around with saving the state of
LRO in the driver, but it just didn't seem worthwhile and would require
a small change to dev_disable_lro() that I did not like.

This patch simply leaves LRO disabled when setting rx-usecs >0 and
requires that the user enable it again.  An extra informational message
will also now appear in the log so users can understand why LRO isn't
being enabled as they expect.

Inconsistency of LRO setting first noticed by Stanislaw Gruszka.

We are seeing some race conditions between incoming station management
requests (station add/remove) and the internal unassoc RXON command that
modifies station table. Modify these flows to require the mutex to be held
and thus serializing them.

This fixes http://bugzilla.intellinuxwireless.org/show_bug.cgi?id=2207

Subject: iwlagn: verify flow id in compressed BA packet

The flow id (scd_flow) in a compressed BA packet should match the txq_id
of the queue from which the aggregated packets were sent. However, in
some hardware like the 1000 series, sometimes the flow id is 0 for the
txq_id (10 to 19). This can cause the annoying message:
[ 2213.306191] iwlagn 0000:01:00.0: Received BA when not expected
[ 2213.310178] iwlagn 0000:01:00.0: Read index for DMA queue txq id (0),
index 5, is out of range [0-256] 7 7.

And even worse, if agg->wait_for_ba is true when the bad BA is arriving,
this can cause system hang due to NULL pointer dereference because the
code is operating in a wrong tx queue!

Subject: TPM: ReadPubEK output struct fix

This patch adds a missing element of the ReadPubEK command output,
that prevents future overflow of this buffer when copying the
TPM output result into it.

Prevents a kernel panic in case the user tries to read the
pubek from sysfs.

Subject: powerpc: Move kdump default base address to 64MB on 64bit

We are seeing boot fails on some System p machines when using the kdump
crashkernel= boot option. The default kdump base address is 32MB, so if we
reserve 256MB for kdump then we reserve all of the RMO except the first 32MB.

We really want kdump to reserve some memory in the RMO and most of it
elsewhere but that will require more significant changes. For now we can shift
the default base address to 64MB when CONFIG_PPC64 and CONFIG_RELOCATABLE are
set. This isn't quite correct since what we really care about is the kdump
kernel is relocatable, but we already make the assumption that base kernel
and kdump kernel have the same CONFIG_RELOCATABLE setting, eg:

#ifndef CONFIG_RELOCATABLE
        if (crashk_res.start != KDUMP_KERNELBASE)
                printk("Crash kernel location must be 0x%x\n",
                                KDUMP_KERNELBASE);
...

RTAS is instantiated towards the top of our RMO, so if we were to go any
higher we risk not having enough RMO memory for the kdump kernel on boxes
with a 128MB RMO.

Subject: powerpc/kexec: Wait for online/possible CPUs only.

kexec_perpare_cpus_wait() iterates i through NR_CPUS to check
paca[i].kexec_state of each to make sure they have quiesced.
However now we have dynamic PACA allocation, paca[NR_CPUS] is not necessarily
valid and we overrun the array;  spurious "cpu is not possible, ignoring"
errors result.  This patch iterates for_each_online_cpu so stays
within the bounds of paca[] -- and every CPU is now 'possible'.

Subject: powerpc: Unconditionally enabled irq stacks

Irq stacks provide an essential protection from stack overflows through
external interrupts, at the cost of two additionals stacks per CPU.

Enable them unconditionally to simplify the kernel build and prevent
people from accidentally disabling them.

Subject: powerpc: rtas_flash needs to use rtas_data_buf

When trying to flash a machine via the update_flash command, Anton received the
following error:

    Restarting system.
    FLASH: kernel bug...flash list header addr above 4GB

The code in question has a comment that the flash list should be in
the kernel data and therefore under 4GB:

        /* NOTE: the "first" block list is a global var with no data
         * blocks in the kernel data segment.  We do this because
         * we want to ensure this block_list addr is under 4GB.
         */

Unfortunately the Kconfig option is marked tristate which means the variable
may not be in the kernel data and could be above 4GB.

Instead of relying on the data segment being below 4GB, use the static
data buffer allocated by the kernel for use by rtas.  Since we don't
use the header struct directly anymore, convert it to a simple pointer.

mpic_resume() on G5 macs blindly dereferences mpic->fixups, but
it may legitimately be NULL (as on PowerMac7,2).  Add an explicit
check.

This fixes suspend-to-disk with one processor (maxcpus=1) for me.

Subject: OMAPFB: LCDC: change update_mode to DISABLED when going suspend

I was observing the following error messages on my OMAP1 based Amstrad Delta
board when first changing from text to graphics mode or vice versa after the
LCD display had been blanked:
	omapfb omapfb: timeout waiting for FRAME DONE
with a followup error message while unblanking it back:
	omapfb omapfb: resetting (status 0xffffffb2,reset count 1)
As a visible result, image pixels happened to be shifted by a few bits,
giving wrong colors.

Examining the code, I found that this problem occures when an OMAP1 internal
LCD controller is disabled from omap_lcdc_suspend() and then a subsequent
omap_lcdc_setup_plane() calls disable_controller() again. This potentially
error provoking behaviour is triggered by the lcdc.update_mode flag being kept
at OMAP_AUTO_UPDATE, regardless of the controller and panel being suspended.

This patch tries to correct the problem by replacing both omap_lcdc_suspend()
and omap_lcdc_resume() function bodies with single calls to
omap_lcdc_set_update_mode() with a respective OMAP_UPDATE_DISABLE or
OMAP_AUTO_UPDATE argument. As a result, exactly the same lower level
operations are performed, with addition of changing the lcdc.update_mode flag
to a value better suited for the controller state. This prevents any further
calls to disable_controller() from omap_lcdc_setup_plane() while the display
is suspended.

Created against linux-2.6.34-rc7.
Tested on Amstrad Delta.

Subject: intel-iommu: Fix double lock in get_domain_for_dev()

stanse found the following double lock.

In get_domain_for_dev:
  spin_lock_irqsave(&device_domain_lock, flags);
  domain_exit(domain);
    domain_remove_dev_info(domain);
      spin_lock_irqsave(&device_domain_lock, flags);
      spin_unlock_irqrestore(&device_domain_lock, flags);
  spin_unlock_irqrestore(&device_domain_lock, flags);

This happens when the domain is created by another CPU at the same time
as this function is creating one, and the other CPU wins the race to
attach it to the device in question, so we have to destroy our own
newly-created one.

Subject: intel-iommu: Force-disable IOMMU for iGFX on broken Cantiga
 revisions.

Certain revisions of this chipset appear to be broken. There is a shadow
GTT which mirrors the real GTT but contains pre-translated physical
addresses, for performance reasons. When a GTT update happens, the
translations are done once and the resulting physical addresses written
back to the shadow GTT.

Except sometimes, the physical address is actually written back to the
_real_ GTT, not the shadow GTT. Thus we start to see faults when that
physical address is fed through translation again.

Subject: kbuild: fix LOCALVERSION handling to match description

In the commit below the version string handling was modified, adding
a '+' where no other version information was supplied:

    commit 85a256d8e0116c8f5ad276730830f5d4d473344d
    Author: David Rientjes <rientjes@google.com>
    Date:   Wed Jan 13 13:01:05 2010 -0800

From the commit the intent was as below:

     - when CONFIG_LOCALVERSION_AUTO is disabled, a `+' is appended if the
       repository has been revised beyond a tagged commit and LOCALVERSION=
       was not passed to "make".

However if the user supplies an empty LOCALVERSION on the command line
the plus suffix is still added.  This form is useful in the case where
the build environment knows that the version as specified is correct and
complete but does not correspond to a specific tag.

This patch changes the implementation to match the documentation
such that specifying LOCALVERSION= on the build line is sufficient
to suppress any suffix.

Subject: ASoC: DaVinci: Fix McASP hardware FIFO configuration

On DA830/OMAP-L137 and DA850/OMAP-L138 SoCs, the McASP peripheral
has FIFO support. This FIFO provides additional data buffering. It
also provides tolerance to variation in host/DMA controller response
times. More details of the FIFO operation can be found at

http://focus.ti.com/general/docs/lit/getliterature.tsp?literatureNumber=sprufm1&fileType=pdf

Existing sequence of steps for audio playback/capture are:
a. DMA configuration
b. McASP configuration (configures and enables FIFO)
c. Start DMA
d. Start McASP (enables FIFO)

During McASP configuration, while FIFO was being configured, FIFO
was being enabled in davinci_hw_common_param() function of
sound/soc/davinci/davinci-mcasp.c file. This generated a transmit
DMA event, which gets serviced when DMA is started.

https://patchwork.kernel.org/patch/84611/ patch clears the DMA
events before starting DMA, which is the right thing to do. But
this resulted in a state where DMA was waiting for an event from
McASP (after step c above), but the event which was already there,
has got cleared (because of step b above).

The fix is not to enable the FIFO during McASP configuration as
FIFO was being enabled as part of McASP start.

Subject: alpha: Detect Super IO chip, no IDE on Avanti, enable EPP19

This patch probes for the Super IO chip and reserves the IO range when
found. It avoids enabling the IDE interface on the Avanti family, since
none has IDE. It enables the Enhanced Parallel Port v1.9 feature.

Subject: alpha: Fix de2104x driver failing to readout MAC address correctly

This patch fixes a missing read memory barrier that is needed for the
driver to readout the MAC address correctly from the on-board ROM.
Also it replaces the use of the deprecated functions readl()/writel().

Subject: powerpc/5200: fix oops during going to standby

When going to standby mode mpc code maps the whole soc5200 node
to access warious MBAR registers. However as of_iomap uses 'reg'
property of device node, only small part of MBAR is getting mapped.
Thus pm code gets oops when trying to access high parts of MBAR.
As a way to overcome this, make mpc52xx_pm_prepare() explicitly
map whole MBAR (0xc0000).

Subject: powerpc/5200: fix lite5200 ethernet phy address

According to my schematics, on Lite5200 board ethernet phy uses address
0 (all ADDR lines are pulled down). With this change I can talk to
onboard phy (LXT971) and correctly use autonegotiation.

Subject: cifs: move cifs_new_fileinfo call out of cifs_posix_open

Having cifs_posix_open call cifs_new_fileinfo is problematic and
inconsistent with how "regular" opens work. It's also buggy as
cifs_reopen_file calls this function on a reconnect, which creates a new
struct cifsFileInfo that just gets leaked.

Push it out into the callers. This also allows us to get rid of the
"mnt" arg to cifs_posix_open.

Finally, in the event that a cifsFileInfo isn't or can't be created, we
always want to close the filehandle out on the server as the client
won't have a record of the filehandle and can't actually use it. Make
sure that CIFSSMBClose is called in those cases.

Subject: cifs: pass instantiated filp back after open call

The current scheme of sticking open files on a list and assuming that
cifs_open will scoop them off of it is broken and leads to "Busy
inodes after umount..." errors at unmount time.

The problem is that there is no guarantee that cifs_open will always
be called after a ->lookup or ->create operation. If there are
permissions or other problems, then it's quite likely that it *won't*
be called.

Fix this by fully instantiating the filp whenever the file is created
and pass that filp back to the VFS. If there is a problem, the VFS
can clean up the references.

Subject: cifs: don't call cifs_new_fileinfo unless cifs_open succeeds

It's currently possible for cifs_open to fail after it has already
called cifs_new_fileinfo. In that situation, the new fileinfo will be
leaked as the caller doesn't call fput. That in turn leads to a busy
inodes after umount problem since the fileinfo holds an extra inode
reference now. Shuffle cifs_open around a bit so that it only calls
cifs_new_fileinfo if it's going to succeed.

Subject: cifs: remove bogus first_time check in NTLMv2 session setup code

This bug appears to be the result of a cut-and-paste mistake from the
NTLMv1 code. The function to generate the MAC key was commented out, but
not the conditional above it. The conditional then ended up causing the
session setup key not to be copied to the buffer unless this was the
first session on the socket, and that made all but the first NTLMv2
session setup fail.

Fix this by removing the conditional and all of the commented clutter
that made it difficult to see.

Subject: gianfar: Fix setup of RX time stamping

Previously the RCTRL_TS_ENABLE bit was set unconditionally. However, if
the RCTRL_TS_ENABLE is set without TMR_CTRL[TE], the driver does not work
properly on some boards (Anton had problems with the MPC8313ERDB and
MPC8568EMDS).

With this patch the bit will only be set if requested from user space
with the SIOCSHWTSTAMP ioctl command, meaning that time stamping is
disabled during normal operation. Users who are not interested in time
stamps will not experience problems with buggy CPU revisions or
performance drops any more.

The setting of TMR_CTRL[TE] is still up to the user. This is considered
safe because users wanting HW timestamps must initialize the eTSEC clock
first anyway, e.g. with the recently submitted PTP clock driver.

Subject: Clear IFF_XMIT_DST_RELEASE for teql interfaces

https://bugzilla.kernel.org/show_bug.cgi?id=16183

The sch_teql module, which can be used to load balance over a set of
underlying interfaces, stopped working after 2.6.30 and has been
broken in all kernels since then for any underlying interface which
requires the addition of link level headers.

The problem is that the transmit routine relies on being able to
access the destination address in the skb in order to do address
resolution once it has decided which underlying interface it is going
to transmit through.

In 2.6.31 the IFF_XMIT_DST_RELEASE flag was introduced, and set by
default for all interfaces, which causes the destination address to be
released before the transmit routine for the interface is called.

The solution is to clear that flag for teql interfaces.

In the eHEA poll function an rmb() is required. Without that some packets

Subject: ehea: Fix kernel deadlock in DLPAR-mem processing

Port reset operations and memory add/remove operations need to
be serialized to avoid a kernel deadlock. The deadlock is caused
by calling the napi_disable() function twice.
Therefore we have to employ the dlpar_mem_lock in the ehea_reset_port
function as well

Subject: gianfar: Fix oversized packets handling

Issuing the following command on host:

$ ifconfig eth2 mtu 1600 ; ping 10.0.0.27 -s 1485 -c 1

Makes some boards (tested with MPC8315 rev 1.1 and MPC8313 rev 1.0)
oops like this:

  [c0339dc0] [c01976e8] gfar_poll+0x170/0x1bc

Dumped buffer descriptors showed that eTSEC's length/truncation
logic sometimes passes oversized packets, i.e. for the above ICMP
packet the following two buffer descriptors may become ready:

  status=1400 length=1536
  status=1800 length=1541

So, it seems that gianfar actually receives the whole big frame,
and it tries to place the packet into two BDs. This situation
confuses the driver, and so the skb_put() sanity check fails.

This patch fixes the issue by adding an appropriate check, i.e.
the driver should not try to process frames with buffer
descriptor's length over rx_buffer_size (i.e. maxfrm and mrblr).

Note that sometimes eTSEC works correctly, i.e. in the second
(last) buffer descriptor bits 'truncated' and 'crcerr' are set,
and so there's no oops. Though I couldn't find any logic when
it works correctly and when not.

Subject: perf session: Remove threads from tree on PERF_RECORD_EXIT
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Move them to a session->dead_threads list just like we do with maps that
are replaced, because we may have hist_entries pointing to them.

This fixes a bug when inserting maps for a new thread that reused the
TID, mixing maps for two different threads, causing an endless loop.

The code for insering maps should be made more robust but for .35 this
is the minimalistic patch.

Subject: bnx2: fix dma_get_ops compilation breakage

This removes dma_get_ops() prefetch optimization in bnx2.

bnx2 uses dma_get_ops() to see if dma_sync_single_for_cpu() is
noop. bnx2 does prefetch if it's noop.

But dma_get_ops() isn't available on all the architectures (only the
architectures that uses dma_map_ops struct have it). Using
dma_get_ops() in drivers leads to compilation breakage on many
architectures.

This patch removes dma_get_ops() and changes bnx2 to do prefetch on
all the architectures. This adds useless prefetch on non-coherent
architectures but this is harmless. It is also unlikely to cause the
performance drop.

Subject: ACPI / PM: Do not enable GPEs for system wakeup in advance

After commit 9630bdd9b15d2f489c646d8bc04b60e53eb5ec78
(ACPI: Use GPE reference counting to support shared GPEs) the wakeup
enable mask bits of GPEs are set as soon as the GPEs are enabled to
wake up the system.  Unfortunately, this leads to a regression
reported by Michal Hocko, where a system is woken up from ACPI S5 by
a device that is not supposed to do that, because the wakeup enable
mask bit of this device's GPE is always set when
acpi_enter_sleep_state() calls acpi_hw_enable_all_wakeup_gpes(),
although it should only be set if the device is supposed to wake up
the system from the target state.

To work around this issue, rework the ACPI power management code so
that GPEs are not enabled to wake up the system upfront, but only
during a system state transition when the target state of the system
is known.  [Of course, this means that the reference counting of
"wakeup" GPEs doesn't really make sense and it is sufficient to
set/unset the wakeup mask bits for them during system sleep
transitions.  This will allow us to simplify the GPE handling code
quite a bit, but that change is too intrusive for 2.6.35.]

Subject: perf record: prevent kill(0, SIGTERM);
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

At exit, perf record will kill the process it was profiling by sending a
SIGTERM to child_pid (if it had been initialised), but in certain situations
child_pid may be 0 and perf would mistakenly kill more processes than intended.

child_pid is set to the return of fork() to either 0 or the pid of the child.
Ordinarily this would not present an issue as the child calls execvp to spawn
the process to be profiled and would therefore never run it's sig_atexit and
never attempt to kill pid 0.

However, if a nonexistant binary had been passed in to perf record the call to
execvp would fail and child_pid would be left set to 0. The child would then
exit and it's atexit handler, finding that child_pid was initialised to 0,
would call kill(0, SIGTERM), resulting in every process within it's process
group being killed.

In the case that perf was being run directly from the shell this typically
would not be an issue as the shell isolates the process.  However, if perf was
being called from another program it could kill unexpected processes, which may
even include X.

This patch changes the logic of the test for whether child_pid was initialised
to only consider positive pids as valid, thereby never attempting to kill pid
0.

Subject: nohz: Fix nohz ratelimit

Chris Wedgwood reports that 39c0cbe (sched: Rate-limit nohz) causes a
serial console regression, unresponsiveness, and indeed it does. The
reason is that the nohz code is skipped even when the tick was already
stopped before the nohz_ratelimit(cpu) condition changed.

Move the nohz_ratelimit() check to the other conditions which prevent
long idle sleeps.

Subject: bridge: fdb cleanup runs too often

It is common in end-node, non STP bridges to set forwarding
delay to zero; which causes the forwarding database cleanup
to run every clock tick. Change to run only as soon as needed
or at next ageing timer interval which ever is sooner.

Use round_jiffies_up macro rather than attempting round up
by changing value.

Subject: sched: Fix over-scheduling bug

Commit e70971591 ("sched: Optimize unused cgroup configuration") introduced
an imbalanced scheduling bug.

If we do not use CGROUP, function update_h_load won't update h_load. When the
system has a large number of tasks far more than logical CPU number, the
incorrect cfs_rq[cpu]->h_load value will cause load_balance() to pull too
many tasks to the local CPU from the busiest CPU. So the busiest CPU keeps
going in a round robin. That will hurt performance.

The issue was found originally by a scientific calculation workload that
developed by Yanmin. With that commit, the workload performance drops
about 40%.

Subject: percpu: fix first chunk match in per_cpu_ptr_to_phys()

per_cpu_ptr_to_phys() determines whether the passed in @addr belongs
to the first_chunk or not by just matching the address against the
address range of the base unit (unit0, used by cpu0).  When an adress
from another cpu was passed in, it will always determine that the
address doesn't belong to the first chunk even when it does.  This
makes the function return a bogus physical address which may lead to
crash.

This problem was discovered by Cliff Wickman while investigating a
crash during kdump on a SGI UV system.

Subject: PCI/PM: Do not use native PCIe PME by default
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Commit c7f486567c1d0acd2e4166c47069835b9f75e77b
(PCI PM: PCIe PME root port service driver) causes the native PCIe
PME signaling to be used by default, if the BIOS allows the kernel to
control the standard configuration registers of PCIe root ports.
However, the native PCIe PME is coupled to the native PCIe hotplug
and calling pcie_pme_acpi_setup() makes some BIOSes expect that
the native PCIe hotplug will be used as well.  That, in turn, causes
problems to appear on systems where the PCIe hotplug driver is not
loaded.  The usual symptom, as reported by Jaroslav Kameník and
others, is that the ACPI GPE associated with PCIe hotplug keeps
firing continuously causing kacpid to take substantial percentage
of CPU time.

To work around this issue, change the default so that the native
PCIe PME signaling is only used if directly requested with the help
of the pcie_pme= command line switch.

Fixes https://bugzilla.kernel.org/show_bug.cgi?id=15924 , which is
a listed regression from 2.6.33.

Subject: ath5k: initialize ah->ah_current_channel

ath5k assumes ah_current_channel is always a valid pointer in
several places, but a newly created interface may not have a
channel.  To avoid null pointer dereferences, set it up to point
to the first available channel until later reconfigured.

This fixes the following oops:

$ insmod ath5k
$ iw phy0 set distance 11000

swapping for CPU models 64 and later. I recently had a report about
a Sempron 3200+, model 95, for which this patch broke temperature
reading. It happens that this is a single-core processor, so the
effect of the swapping was to read a temperature value for a core
that didn't exist, leading to an incorrect value (-49 degrees C.)

Disabling core swapping on singe-core processors should fix this.

Additional comment from Andreas:

The BKDG says

  Thermal Sensor Core Select (ThermSenseCoreSel)-Bit 2. This bit
  selects the CPU whose temperature is reported in the CurTemp
  field. This bit only applies to dual core processors. For
  single core processors CPU0 Thermal Sensor is always selected.

k8temp_probe() correctly detected that SEL_CORE can't be used on single
core CPU. Thus k8temp did never update the temperature values stored
in temp[1][x] and -49 degrees was reported. For single core CPUs we
must use the values read into temp[0][x].

Subject: ALSA: usb/endpoint, fix dangling pointer use

Stanse found that in snd_usb_parse_audio_endpoints, there is a
dangling pointer dereference. When snd_usb_parse_audio_format fails,
fp is freed, and continue invoked. On the next loop, there is
"fp && fp->altsetting == 1 && fp->channels == 1" test, but fp is set
from the last iteration (but is bogus) and thus ilegally dereferenced.

Set fp to NULL before "continue".

Subject: udp: Fix bogus UFO packet generation

It has been reported that the new UFO software fallback path
fails under certain conditions with NFS.  I tracked the problem
down to the generation of UFO packets that are smaller than the
MTU.  The software fallback path simply discards these packets.

This patch fixes the problem by not generating such packets on
the UFO path.

when SERIO_I8042=m, SERIO_LIBPS2=y, KEYBOARD_ATKBD=y.

atkbd on Moorestown even when !CONFIG_EMBEDDED.

Subject: virtio-pci: disable msi at startup

virtio-pci resets the device at startup by writing to the status
register, but this does not clear the pci config space,
specifically msi enable status which affects register
layout.

This breaks things like kdump when they try to use e.g. virtio-blk.

Fix by forcing msi off at startup. Since pci.c already has
a routine to do this, we export and use it instead of duplicating code.

Subject: rcu: apply RCU protection to wake_affine()

The task_group() function returns a pointer that must be protected
by either RCU, the ->alloc_lock, or the cgroup lock (see the
rcu_dereference_check() in task_subsys_state(), which is invoked by
task_group()).  The wake_affine() function currently does none of these,
which means that a concurrent update would be within its rights to free
the structure returned by task_group().  Because wake_affine() uses this
structure only to compute load-balancing heuristics, there is no reason
to acquire either of the two locks.

Therefore, this commit introduces an RCU read-side critical section that
starts before the first call to task_group() and ends after the last use
of the "tg" pointer returned from task_group().  Thanks to Li Zefan for
pointing out the need to extend the RCU read-side critical section from
that proposed by the original patch.

Subject: snmp: fix SNMP_ADD_STATS()

commit aa2ea0586d9d (tcp: fix outsegs stat for TSO segments) incorrectly
assumed SNMP_ADD_STATS() was used from BH context.

Fix this using mib[!in_softirq()] instead of mib[0]

Subject: sky2: enable rx/tx in sky2_phy_reinit()

sky2_phy_reinit is called by the ethtool helpers sky2_set_settings,
sky2_nway_reset and sky2_set_pauseparam when netif_running.

However, at the end of sky2_phy_init GM_GP_CTRL has GM_GPCR_RX_ENA and
GM_GPCR_TX_ENA cleared. So, doing these commands causes the device to
stop working:

$ ethtool -r eth0
$ ethtool -A eth0 autoneg off

Fix this issue by enabling Rx/Tx after running sky2_phy_init in
sky2_phy_reinit.

Subject: sched: silence PROVE_RCU in sched_fork()

Because cgroup_fork() is ran before sched_fork() [ from copy_process() ]
and the child's pid is not yet visible the child is pinned to its
cgroup. Therefore we can silence this warning.

A nicer solution would be moving cgroup_fork() to right after
dup_task_struct() and exclude PF_STARTING from task_subsys_state().

Subject: Restore partition detection of newly created md arrays.

Commit  b821eaa572fd737faaf6928ba046e571526c36c6 broke partition
detection for md arrays.

The logic was almost right.  However if revalidate_disk is called
when the device is not yet open, bdev->bd_disk won't be set, so the
flush_disk() Call will not set bd_invalidated.

So when md_open is called we still need to ensure that
->bd_invalidated gets set.  This is easily done with a call to
check_disk_size_change in the place where the offending commit removed
check_disk_change.  At the important times, the size will have changed
from 0 to non-zero, so check_disk_size_change will set bd_invalidated.

Subject: md: fix handling of array level takeover that re-arranges devices.

Most array level changes leave the list of devices largely unchanged,
possibly causing one at the end to become redundant.
However conversions between RAID0 and RAID10 need to renumber
all devices (except 0).

This renumbering is currently being done in the ->run method when the
new personality takes over.  However this is too late as the common
code in md.c might already have invalidated some of the devices if
they had a ->raid_disk number that appeared to high.

Moving it into the ->takeover method is too early as the array is
still active at that time and wrong ->raid_disk numbers could cause
confusion.

So add a ->new_raid_disk field to mdk_rdev_s and use it to communicate
the new raid_disk number.
Now the common code knows exactly which devices need to be renumbered,
and which can be invalidated, and can do it all at a convenient time
when the array is suspend.
It can also update some symlinks in sysfs which previously were not be
updated correctly.

Subject: md/raid5: avoid oops when number of devices is reduced then
 increased.

The entries in the stripe_cache maintained by raid5 are enlarged
when we increased the number of devices in the array, but not
shrunk when we reduce the number of devices.
So if entries are added after reducing the number of devices, we
much ensure to initialise the whole entry, not just the part that
is currently relevant.  Otherwise if we enlarge the array again,
we will reference uninitialised values.

As grow_buffers/shrink_buffer now want to use a count that is stored
explicity in the raid_conf, they should get it from there rather than
being passed it as a parameter.

Subject: md: Don't update ->recovery_offset when reshaping an array to fewer
 devices.

When an array is reshaped to have fewer devices, the reshape proceeds
from the end of the devices to the beginning.

If a device happens to be non-In_sync (which is possible but rare)
we would normally update the ->recovery_offset as the reshape
progresses. However that would be wrong as the recover_offset records
that the early part of the device is in_sync, while in fact it would
only be the later part that is in_sync, and in any case the offset
number would be measured from the wrong end of the device.

Relatedly, if after a reshape a spare is discovered to not be
recoverred all the way to the end, not allow spare_active
to incorporate it in the array.

This becomes relevant in the following sample scenario:

A 4 drive RAID5 is converted to a 6 drive RAID6 in a combined
operation.
The RAID5->RAID6 conversion will cause a 5 drive to be included as a
spare, then the 5drive -> 6drive reshape will effectively rebuild that
spare as it progresses.  The 6th drive is treated as in_sync the whole
time as there is never any case that we might consider reading from
it, but must not because there is no valid data.

If we interrupt this reshape part-way through and reverse it to return
to a 5-drive RAID6 (or event a 4-drive RAID5), we don't want to update
the recovery_offset - as that would be wrong - and we don't want to
include that spare as active in the 5-drive RAID6 when the reversed
reshape completed and it will be mostly out-of-sync still.

Subject: md/raid5: More careful check for "has array failed".

When we are reshaping an array, the device failure combinations
that cause us to decide that the array as failed are more subtle.

In particular, any 'spare' will be fully in-sync in the section
of the array that has already been reshaped, thus failures that
affect only that section are less critical.

So encode this subtlety in a new function and call it as appropriate.

The case that showed this problem was a 4 drive RAID5 to 8 drive RAID6
conversion where the last two devices failed.
This resulted in:

  good good good good incomplete good good failed failed

while converting a 5-drive RAID6 to 8 drive RAID5
The incomplete device causes the whole array to look bad,
bad as it was actually good for the section that had been
converted to 8-drives, all the data was actually safe.

Subject: md/raid5: Allow recovered part of partially recovered devices to be
 in-sync

During a recovery of reshape the early part of some devices might be
in-sync while the later parts are not.
We we know we are looking at an early part it is good to treat that
part as in-sync for stripe calculations.

This is particularly important for a reshape which suffers device
failure.  Treating the data as in-sync can mean the difference between
data-safety and data-loss.

Subject: md/raid5: add a missing 'continue' in a loop.

As the comment says, the tail of this loop only applies to devices
that are not fully in sync, so if In_sync was set, we should avoid
the rest of the loop.

This bug will hardly ever cause an actual problem.  The worst it
can do is allow an array to be assembled that is dirty and degraded,
which is not generally a good idea (without warning the sysadmin
first).

This will only happen if the array is RAID4 or a RAID5/6 in an
intermediate state during a reshape and so has one drive that is
all 'parity' - no data - while some other device has failed.

This is certainly possible, but not at all common.

Subject: md/raid5: don't include 'spare' drives when reshaping to fewer
 devices.

There are few situations where it would make any sense to add a spare
when reducing the number of devices in an array, but it is
conceivable:  A 6 drive RAID6 with two missing devices could be
reshaped to a 5 drive RAID6, and a spare could become available
just in time for the reshape, but not early enough to have been
recovered first.  'freezing' recovery can make this easy to
do without any races.

However doing such a thing is a bad idea.  md will not record the
partially-recovered state of the 'spare' and when the reshape
finished it will think that the spare is still spare.
Easiest way to avoid this confusion is to simply disallow it.

MIME-Version: 1.0

Content-Transfer-Encoding: 8bit

Fix the bundle validation code to not assume having a valid policy.
When we have multiple transformations for a xfrm policy, the bundle
instance will be a chain of bundles with only the first one having
the policy reference. When policy_genid is bumped it will expire the
first bundle in the chain which is equivalent of expiring the whole
chain.

Subject: ipv6: fix NULL reference in proxy neighbor discovery

The addition of TLLAO option created a kernel OOPS regression
for the case where neighbor advertisement is being sent via
proxy path.  When using proxy, ipv6_get_ifaddr() returns NULL
causing the NULL dereference.

Change causing the bug was:
commit f7734fdf61ec6bb848e0bafc1fb8bad2c124bb50
Author: Octavian Purdila <opurdila@ixiacom.com>
Date:   Fri Oct 2 11:39:15 2009 +0000

    make TLLAO option for NA packets configurable

Subject: isdn/gigaset: honor CAPI application's buffer size request

Fix the Gigaset CAPI driver to limit the length of a connection's
payload data receive buffers to the corresponding CAPI application's
data buffer size, as some real-life CAPI applications tend to be
rather unhappy if they receive bigger data blocks than requested.

Subject: isdn/gigaset: correct CAPI voice connection encoding

Make the Gigaset CAPI driver select L2_VOICE (AT^SBPR=2) as the
layer 2 encoding for transparent connections, like the ISDN4Linux
variant.  L2_BITSYNC (AT^SBPR=0) mutes internal connections and
distorts external ones.

Subject: isdn/gigaset: correct CAPI DATA_B3 Delivery Confirmation

The Gigaset CAPI driver handled all DATA_B3_REQ messages as if the
Delivery Confirmation flag bit was set, delaying the emission of the
DATA_B3_CONF reply until the data was actually transmitted. Some
CAPI applications (notably Asterisk) aren't happy with that
behaviour. Change it to actually evaluate the Delivery Confirmation
flag as described the CAPI specification.

Subject: isdn/gigaset: encode HLC and BC together

Adapt to buggy device firmware which accepts setting HLC only in the
same command line as BC, by encoding HLC and BC in a single command
if both are specified, and rejecting HLC without BC.

Store the connection state in the channel structure instead.

Subject: vxge: fix memory leak in vxge_alloc_msix() error path

When pci_enable_msix() returned ret<0, entries and vxge_entries were leaked.
While at it, use the centralized exit idiom in the function.

Subject: ISDN: hysdn, fix potential NULL dereference

Stanse found that lp is dereferenced earlier than checked for being
NULL in hysdn_rx_netpkt. Move the initialization below the test.

Subject: KEYS: Propagate error code instead of returning -EINVAL

This is from a Smatch check I'm writing.

strncpy_from_user() returns -EFAULT on error so the first change just
silences a warning but doesn't change how the code works.

The other change is a bug fix because install_thread_keyring_to_cred()
can return a variety of errors such as -EINVAL, -EEXIST, -ENOMEM or
-EKEYREVOKED.
