2012-06-01ARM: ux500: Enable probing of pinctrl through Device TreeLee Jones
The Nomadik GPIO controller now relies on Nomadik pinctrl, however the pinctrl driver is not currently started by any ux500 platform. This is requred or GPIOs do not work at all.

2012-06-01ARM: ux500: Add support for ab8500 regulators into the Device TreeLee Jones
Here we supply the information required to setup regulators successfully on Snowball and other db8500 variants which use the ab8500 regulators. Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
2012-06-01ARM: ux500: Provide regulator support for SMSC911x via Device TreeLee Jones
This patch adds a fixed regulator for use by the SMSC911x Ethernet chip driver into the db8500 Device Tree. It also references other regulators required by the same device.

2012-06-01ARM: ux500: Allow PRCMU regulator to be probed during a DT enabled bootLee Jones
This patch adds the correct compatible string for use during Device Tree population. Without it the DB8500 PRCMU regulators would be processed when DT is enabled.

2012-06-01ARM: ux500: Apply db8500-prcmu regulator information to db8500 Device TreeLee Jones
Here we inform Device Tree of which regulators are provided by the db8500- prcmu. This way we can reference some of their consumers directly from the Device Tree e.g. SMSC911x Ethernet chip.

2012-06-01ARM: ux500: Only initialise STE's UIBs on boards which support themLee Jones
ST-Ericsson uses User Interface Boards to extend functionality of some of their development boards. However, these aren't compatible with all the supported boards found in Mainline (Snowball for instance). This patch ensures that the UIBs are only probed on boards which can actually support them. This in turn saves lots of unnecessary error messages normally found in Snowball's boot log.

2012-06-01ARM: ux500: Disable platform setup of the ab8500 when DT is enabledLee Jones
The final piece of the ab8500 puzzle. Here we prevent any of the ab8500-* drivers from being registered from platform code when Device Tree is enabled, as we expect DT do probe each of these individually. We also provide the relevant compatible strings, so that DT knows which nodes it needs to pay attention to during population.

2012-06-01ARM: ux500: Use correct format for dynamic IRQ assignmentLee Jones
This patch applies the correct format requested by the irq domain. For chained IRQs which use GPIO lines as IRQs, we stipulate that a two cell request is required. The first cell contains the requested IRQ and the second can contain flags pertaining to edge detection and level sensitive values. The zeroth cell specifies the GPIO controller by use of a phandle.

2012-06-01ARM: ux500: Re-enable SMSC911x platform code registration during non-DT bootsLee Jones
The patch to disable SMSC911x registration was applied twice in the upstream kernel by mistake. Git interpreted this as 'take the same entry from a similar struct' which was close by. This was the wrong thing to do. This patch rectifies this error and re-enables SMSC911x registration when Device Tree is not enabled.

2012-06-01ARM: ux500: PRCMU related configuration and layout corrections for Device TreeLee Jones

2012-06-01ARM: ux500: Remove DB8500 PRCMU platform registration when DT is enabledLee Jones
Now the DB8500 has Device Tree support it will be probed when the DT is parsed, rendering the requirement for platform registration void. This patch removes DB8500 PRCMU platform registration.

2012-06-01ARM: ux500: Disable SMSC911x platform code registration when DT is enabledLee Jones
Now the SCMC911x is correctly enabled in Device Tree, there is no need to continue registering it from platform code. In fact, if we continue doing so, the system will throw an error on boot.

Pull Sparc updates from David S. Miller: 1) Remove the idiotic situation wherein Leon was a special case in all of the TLB/cache handling code. The worst side effect of this bogosity is that you couldn't build a kernel with Leon support enabled (to get better build coverage), and test boot it on a non-LEON cpu. Leon is, in all core respects, programatically identical to the 32-bit SRMMU. Except that they put the TLB registers in a different alternate address space location. Through code patching (for fast paths) and run time checks, this issue is now a thing of the past. From Sam Ravnborg. 2) There was a mis-merge of arch/sparc/Kconfig for one of the clockevents changes that went in, causing 32-bit sparc to start failing to build. I merged in your tree to get those clockevents changes (and added a note to the merge commit) then added Stephen Rothwell's fix for the merge error. 3) Software quad floating point emulation was not working properly on more recent Niagara chips, because the way the situation is reported by the cpu has changed. Nobody noticed because gcc emits calls to software emulation routines in glibc. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/sparc: (25 commits) sparc: fix sparc64 build due to leon.h inclusion sparc32: remove unused variable in head_32.S sparc32,leon: fix leon bootup sparc32: Export leon_dma_ops to modules. sparc32: support leon + sun in dma_make_coherent() sparc32,leon: always support leon in ioport sparc32,leon: always include leon_pmc in build sparc32: refactor cpu_idle() sparc32: srmmu_probe now knows about leon too sparc32: drop LEON hack for ASI_M_MMUREGS sparc32: introduce run-time patching of srmmu access functions sparc32: introduce support for run-time patching for all shared assembler code sparc32,leon: fix section mismatch warning sparc32,leon: always include leon_smp + leon_mm in build sparc32,leon: always include leon_kernel in build sparc32,leon: clean up leon.h sparc32: handle leon in cpu.c sparc32: handle leon in irq_32.c sparc32: add support for run-time patching of leon/sun single instructions sparc32: introduce sparc32_start_kernel called from head_32.S ...

Stub out MSR methods that aren't actually needed. This fixes a crash as Xen Dom0 on AMD Trinity systems. A bigger patch should be added to remove the paravirt machinery completely for the methods which apparently have no users!

2012-05-30net/smsc911x: Repair broken failure pathsLee Jones
Current failure paths attempt to free resources which we failed to request and disable resources which we failed to enable ones. This leads to kernel oops/panic. This patch does some simple re-ordering to prevent this from happening.

Use unsigned long for dealing with jiffies not int. Rename the callback to something sensible. Use __this_cpu_read/write for accessing per cpu data. Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Acked-by: Borislav Petkov <borislav.petkov@amd.com> Signed-off-by: Tony Luck <tony.luck@intel.com>
2012-05-30x86, mtrr: Fix a type overflow in range_to_mtrr funczhenzhong.duan
When boot on sun G5+ with 4T mem, see an overflow in mtrr cleanup as below. *BAD*gran_size: 2G chunk_size: 2G num_reg: 10 lose cover RAM: -18014398505283592M This is because 1<<31 sign extended. Use an unsigned long constant to fix it. Useful for mem larger than or equal to 4T. -v2: Use 64bit constant instead of explicit type conversion as suggested by Yinghai. Description updated too.

2012-05-30virtio-net: remove useless disable on freezeMichael S. Tsirkin
disable_cb is just an optimization: it can not guarantee that there are no callbacks. In particular it doesn't have any effect when event index is on. Instead, detach, napi disable and reset on freeze ensure we don't run concurrently with a callback. Remove the useless calls so we get same behaviour with and without event index.
