With the pending NO_IRQ cleanup, this will lead to a warning at boot time, since -1 is obviously broken. This patch updates the interrupt used for GPIO0 to match that specified by the TRM. Unfortunately, it's not clear how to trigger this interrupt so we trust that the documentation is correct.

The forceful re-enablement of IRQs after pm_idle has returned can go. The warning certainly doesn't trigger for existing users. To get rid of the pm_idle calling convention oddity, let's introduce arm_pm_idle() allowing for the local_irq_enable() to be factored out from SOC specific implementations. The default pm_idle function becomes a wrapper for arm_pm_idle and it takes care of enabling IRQs closer to where they are initially disabled. And finally move the comment explaining the reason for that turning off of IRQs to a more proper location.

The most interesting bits of the series are: * A fix to the timer code whereby the shortest trigger period is set to 100 cycles; previously, it was possible to set this to 1 cycle, but by the time the register was written, that time had already passed and the timer interrupt would not go off until the cycle counter had gone a full cycle. * Allowing a device tree binary to be passed in to the kernel from u-boot. The OpenRISC architecture has been recently merged into upstream u-boot, so this change gets OpenRISC Linux into sync with that project." * tag 'for-3.4' of git://openrisc.net/jonas/linux: OpenRISC: Remove memory_start/end prototypes openrisc: remove semicolon from KSTK_ defs openrisc: sanitize use of orig_gpr11 openrisc: fix virt_addr_valid OpenRISC: Export dump_stack() OpenRISC: Select GENERIC_ATOMIC64 openrisc: Set shortest clock event to 100 ticks openrisc: included linux/thread_info.h twice OpenRISC: Use set_current_blocked() and block_sigmask() OpenRISC: Don't mask signals if we fail to setup signal stack OpenRISC: No need to reset handler if SA_ONESHOT OpenRISC: Don't reimplement force_sigsegv() openrisc: enable passing of flattened device tree pointer arch/openrisc/mm/init.c: trivial: use BUG_ON

| * | | | | | | | | openrisc: Set shortest clock event to 100 ticksJonas Bonn2012-02-17

Not quite sure how many clock cycles it actually takes to get through to actually writing the register, but 100 seems to work reliably. Use generic helper to set up the clock event while we're at it.

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.
