2012-05-22Merge tag 'soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-socLinus Torvalds
Pull support for new arm SoCs from Olof Johansson: "Three new system-on-chip models are supported: the st-ericsson u9540 in ux500, the sam9n12 in at91 and the emma ev2 in shmobile. Emma is a little bit special because it is completely unrelated to the classic shmobile models, but the new Renesas rmobile SoCs are a combination of things from both Emma and shmobile, so it was decided to have them all live in one directory. This also contains updates to existing shmobile soc code as well as some related board changes due to dependencies." * tag 'soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (23 commits) mach-shmobile: Use DT_MACHINE for KZM9D V3 mach-shmobile: Emma Mobile EV2 DT support V3 mach-shmobile: KZM9D board Ethernet support V3 mach-shmobile: Emma Mobile EV2 GPIO support V3 mach-shmobile: Emma Mobile EV2 SMP support V3 mach-shmobile: KZM9D board support V3 mach-shmobile: Emma Mobile EV2 SoC base support V3 gpio: Emma Mobile GPIO driver V2 ARM: mach-shmobile: sh73a0: fixup PINT/IRQ16-IRQ31 irq number conflict ARM: mach-shmobile: clock-r8a7740: use followparent_recalc on usb24s ARM: mach-shmobile: clock-r8a7740: add MMCIF clock ARM: mach-shmobile: clock-r8a7740: add SDHI clock ARM: mach-shmobile: clock-r8a7740: add USB clock ARM: mach-shmobile: clock-r8a7740: add FSI clock ARM: mach-shmobile: r8a7740: cleanup I2C workaround method ARM: mach-shmobile: r8a7740: add gpio_irq support ARM: mach-shmobile: sh7372: Add FSI DMAEngine support ARM / mach-shmobile: Use preset_lpj with calibrate_delay() ARM: ux500: ioremap differences for DB9540 ARM: ux500: core U9540 support ...
2012-05-22Merge tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-socLinus Torvalds
Pull device tree conversions for arm-soc, part 1, from Olof Johansson: "The spear3xx, lpc32xx, shmobile and mmp platforms are joining the game of booting using device trees, which is a great step forward for them. at91 and spear have pretty much completed this process with a huge amount of work being put into at91. The other platforms are continuing the process. We finally start to see the payback on this investment, as new machines are getting supported purely by adding a .dts source file that can be completely independent of the kernel source."

Pull first batch of arm-soc cleanups from Olof Johansson: "These cleanups are basically all over the place. The idea is to collect changes with minimal impact but large number of changes so we can avoid them from distracting in the diffstat in the other series. A significant number of lines get removed here, in particular because the ixp2000 and ixp23xx platforms get removed. These have never been extremely popular and have fallen into disuse over time with no active maintainer taking care of them. The u5500 soc never made it into a product, so we are removing it from the ux500 platform. Many good cleanups also went into the at91 and omap platforms, as has been the case for a number of releases."

2012-05-22sh: intc: Kill off special reservation interface.Paul Mundt
At present reserving the IRLs in the IRQ bitmap in addition to the dropping of the legacy IRQ pre-allocation prevent IRL IRQs from being allocated for the x3proto board. The only reason to permit reservations was to lock down possible hardware vectors prior to dynamic IRQ scanning, but this doesn't matter much given that the hardware controller configuration is sorted before we get around to doing any dynamic IRQ allocation anyways. Beyond that, all of the tables are __init annotated, so quite a bit more work would need to be done to support reconfiguring things like IRL controllers on the fly, much more than would ever make it worth the hassle.

2012-05-22powerpc: Fix irq distributionKim Phillips
setting CONFIG_IRQ_ALL_CPUS distributes IRQs to CPUs only when the number of online CPUs equals NR_CPUS. See commit 280ff97494e0fef4124bee5c52e39b23a18dd283 "sparc64: fix and optimize irq distribution" for more details.

2012-05-21score: add handling of NOTIFY_RESUME to do_notify_resume()Al Viro
It's already called if TIF_NOTIFY_RESUME is set, so we only need to add the actual work. Note that checking for RESTORE_SIGMASK was not needed - set_restore_sigmask() also sets SIGPENDING, so we never RESTORE_SIGMASK without SIGPENDING. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2012-05-21m68k: add TIF_NOTIFY_RESUME and handle it.Al Viro
TIF_NOTIFY_RESUME added (as bit 5). That way nommu glue needs no changes at all; mmu one needs just to replace jmi do_signal_return to jne do_signal_return There we have flags shifted up, until bit 6 (SIGPENDING) is in MSBit; instead of checking that MSBit is set (jmi) we check that MSBit or something below it is set (jne); bits 0..4 are never set, so that's precisely "bit 6 or bit 5 is set". Usual handling of NOTIFY_RESUME/SIGPENDING is done in do_notify_resume(); glue calls it instead of do_signal(). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2012-05-21m68k: use set_current_blocked() and block_sigmask()Matt Fleming
As described in e6fa16ab ("signal: sigprocmask() should do retarget_shared_pending()") the modification of current->blocked is incorrect as we need to check whether the signal we're about to block is pending in the shared queue. Also, use the new helper function introduced in commit 5e6292c0f28f ("signal: add block_sigmask() for adding sigmask to current->blocked") which centralises the code for updating current->blocked after successfully delivering a signal and reduces the amount of duplicate code across architectures. In the past some architectures got this code wrong, so using this helper function should stop that from happening again.

2012-05-21avr32: don't mask signals in the error pathMatt Fleming
The current handle_signal() implementation is broken - it will mask signals if we fail to setup the signal stack frame, which isn't the desired behaviour, we should only be masking signals if we succeed in setting up the stack frame. It looks like this code was copied from the old (broken) arm implementation but wasn't updated when the arm code was fixed in commit a6c61e9dfdd0 ("[ARM] 3168/1: Update ARM signal delivery and masking").
