It's the only way we'll be able to implement the function
graph tracer properly.
A positive is that we no longer have to worry about the
linker over-optimizing the tail call, since we don't
use a tail call any more.

This keeps us from having to use kstat_irqs_cpu() from the NMI handler,
the former of which is a profiled function.
Instead we use a currently empty slot in the cpu_data

Check function_trace_stop at ftrace_caller
Toss mcount_call and dummy call of ftrace_stub, unnecessary.
Document problems we'll have if the final kernel image link
ever turns on relaxation.
Properly size 'ftrace_call' so it looks right when inspecting
instructions under gdb et al.

If we are in an NMI then doing a plain raw_local_irq_disable() will
write PIL_NORMAL_MAX into %pil, which is lower than PIL_NMI, and thus
we'll re-enable NMIs and recurse.
Doing a simple:
%pil = %pil | PIL_NORMAL_MAX
does what we want, if we're already at PIL_NMI (15) we leave it at
that setting, else we set it to PIL_NORMAL_MAX (14).
This should get the function tracer working on sparc64.

This gets rid of a local function (is_kernel_stack()) which tries to
do the same thing, yet poorly in that it doesn't handle IRQ stacks
properly.

We provide regs->tstate, regs->tpc, regs->tnpc and
regs->u_regs[UREG_FP].
regs->tstate is necessary for:
user_mode() (via perf_exclude_event())
perf_misc_flags() (via perf_prepare_sample())
regs->tpc is necessary for:
perf_instruction_pointer() (via perf_prepare_sample())
and regs->u_regs[UREG_FP] is necessary for:
perf_callchain() (via perf_prepare_sample())
The regs->tnpc value is provided just to be tidy.

* git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc-2.6:
sparc64: Properly truncate pt_regs framepointer in perf callback.
arch/sparc/kernel: Use set_cpus_allowed_ptr
sparc: Fix use of uid16_t and gid16_t in asm/stat.h
|
|
For 32-bit processes, we save the full 64-bits of the regs in pt_regs.
But unlike when the userspace actually does load and store
instructions, the top 32-bits don't get automatically truncated by the
cpu in kernel mode (because the kernel doesn't execute with PSTATE_AM
address masking enabled).
So we have to do it by hand.

Use set_cpus_allowed_ptr rather than set_cpus_allowed.

This patchset transforms the PCI DMA API into the generic device model.
It's one of the reasons why we introduced the generic DMA API long ago;
driver writers are always able to use the generic DMA API with any bus
instead of using bus specific DMA APIs such as pci_map_single,
sbus_map_single, etc (only two bus specific APIs exist now; pci and ssb).
Some of the PCI DMA API are already implented on the top of the generic
DMA API (include/asm-generic/pci-dma-compat.h). But there are some
exceptions. This patchset finishes the transformation.
This patch:
sparc has two dma_set_mask implementations for 32bit and 64bit. They are
same except for the error returned value. We can safely unify them since
the error returned value doesn't matter as long as it is negative (as
DMA-API.txt describes).
This patch also changes dma_set_mask not to call
pci_set_dma_mask. Instead, dma_set_mask does the same thing that
pci_set_dma_mask does. This change enables ut to change
pci_set_dma_mask to call dma_set_mask; we can implement
pci_set_dma_mask as pci-dma-compat.h does.

Add a generic implementation of the ipc demultiplexer syscall. Except for
s390 and sparc64 all implementations of the sys_ipc are nearly identical.
There are slight differences in the types of the parameters, where mips
and powerpc as the only 64-bit architectures with sys_ipc use unsigned
long for the "third" argument as it gets casted to a pointer later, while
it traditionally is an "int" like most other paramters. frv goes even
further and uses unsigned long for all parameters execept for "ptr" which
is a pointer type everywhere. The change from int to unsigned long for
"third" and back to "int" for the others on frv should be fine due to the
in-register calling conventions for syscalls (we already had a similar
issue with the generic sys_ptrace), but I'd prefer to have the arch
maintainers looks over this in details.
Except for that h8300, m68k and m68knommu lack an impplementation of the
semtimedop sub call which this patch adds, and various architectures have
gets used - at least on i386 it seems superflous as the compat code on
x86-64 and ia64 doesn't even bother to implement it.

This makes it easier to extend perf_sample_data and fixes a bug on arm
and sparc, which failed to set ->raw to NULL, which can cause crashes
when combined with PERF_SAMPLE_RAW.
It also optimizes PowerPC and tracepoint, because the struct
initialization is forced to zero out the whole structure.

Now that we return the new resource start position, there is no
need to update "struct resource" inside the align function.
Therefore, mark the struct resource as const.

As suggested by Linus, align functions should return the start
of a resource, not void. An update of "res->start" is no longer
necessary.

This is a partial revert of commit 3ad2f3fbb961 ("tree-wide: Assorted
spelling fixes") as the change in arch/sparc/kernel/leon_kernel.c has
been already fixed while refactoring the file in the sparc tree.

Commit 085219f79cad89291699bd2bfb21c9fdabafe65f
("sparc32: use proper types in struct stat")
Accidently changed the struct stat uid/gid members
to uid_t and gid_t, but those get set to
__kernel_uid32_t and __kernel_gid32_t respectively.
Those are of type 'int' but the structure is meant
to have 'short'. So use uid16_t and gid16_t to
correct this.
