2012-05-31thinkpad-acpi: fix issuing duplicated key events for brightness up/downAlex Hung
The tp_features.bright_acpimode will not be set correctly for brightness control because ACPI_VIDEO_HID will not be located in ACPI. As a result, a duplicated key event will always be sent. acpi_video_backlight_support() is sufficient to detect standard ACPI brightness control.

2012-05-31apple-gmux: Add suspend/resume support for the backlightSeth Forshee

2012-05-31xo1-rfkill: only act when blocked state is changedDaniel Drake
The XO-1 rfkill driver should only send EC commands when changing between blocked/unblocked state. The rfkill switch is asked to be unblocked on every resume (even when the card was never blocked before) and sending a EC_WLAN_LEAVE_RESET command here upsets the resume sequence of the libertas driver. Adding the check to avoid the spurious EC_WLAN_LEAVE_RESET fixes the wifi resume behaviour. The rfkill state is maintained by the hardware over suspend/resume so no extra consideration is needed here.

2012-05-31drivers/x86: mark const init data with __initconst instead of __initdataUwe Kleine-König
As long as there is no other non-const variable marked __initdata in the same compilation unit it doesn't hurt. If there were one however compilation would fail with error: $variablename causes a section type conflict because a section containing const variables is marked read only and so cannot contain non-const variables.

2012-05-31Btrfs: fix tree mod log rewinded level and rewinding of moved keysJan Schmidt
When we rewind REMOVE_WHILE_FREEING operations, there's code that allocates a fresh buffer instead of cloning the old one. Setting that buffer's level correctly was missing in this case.

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 ...

We faced segmentation fault on perf top -G at very high sampling rate due to a corrupted callchain. While the root cause was not revealed (I failed to figure it out), this patch tries to protect us from the segfault on such cases.

2012-05-31perf callchain: Make callchain cursors TLSNamhyung Kim
perf top -G has a race on callchain cursor between main thread and display thread. Since the callchain cursors are used locally make them thread-local data would solve the problem.

2012-05-31drm/i915/crt: Do not rely upon the HPD presence pinChris Wilson
Whilst most monitors do wire up the HPD presence pin, it seems quite a few KVM do not. Therefore if we simply rely on the HPD pin being asserted to indicate a connected monitor we fail miserable, so fall back to performing a DCC query for the EDID.

2012-05-31block: avoid infinite loop in get_task_io_context()Eric Dumazet
Calling get_task_io_context() on a exiting task which isn't %current can loop forever. This triggers at boot time on my dev machine. BUG: soft lockup - CPU#3 stuck for 22s ! [mountall.1603] Fix this by making create_task_io_context() returns -EBUSY in this case to break the loop.
