* Merge tag 'cleanup-initcall' of ↵Linus Torvalds2012-05-2611-2/+72

Fix up trivial conflicts in arch/arm/mach-{exynos/mach-universal_c210.c, imx/mach-cpuimx51.c, omap2/board-generic.c} due to changes nearby (and, in the case of cpuimx51.c the board support being deleted) * tag 'cleanup-initcall' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: ARM: ux500: use machine specific hook for late init ARM: tegra: use machine specific hook for late init ARM: shmobile: use machine specific hook for late init ARM: sa1100: use machine specific hook for late init ARM: s3c64xx: use machine specific hook for late init ARM: prima2: use machine specific hook for late init ARM: pnx4008: use machine specific hook for late init ARM: omap2: use machine specific hook for late init ARM: omap1: use machine specific hook for late init ARM: msm: use machine specific hook for late init ARM: imx: use machine specific hook for late init ARM: exynos: use machine specific hook for late init ARM: ep93xx: use machine specific hook for late init ARM: davinci: use machine specific hook for late init ARM: provide a late_initcall hook for platform initialization

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This teq was first introduced in bcc0f6a ([ARM] msm: clean up iomap and devices, 2008-09-10). It seems that DEBUG_LL support on MSM at the time had to remove the virtual mapping for the uart base. Thus when the MMU was enabled the addruart macro returned 0 and the senduart macro would test for 0 and do nothing. It was a simple way to turn off DEBUG_LL when the MMU was enabled. The virtual mapping was added back in 6339f66 (msm: make debugging UART (for DEBUG_LL) configurable, 2009-11-02) but the patch forgot to remove the teq here. So as it stands the teq has been useless for two years and DEBUG_LL works fine without it.

I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis." Fixed up some conflicts from other header file cleanups and moving code around that has happened in the meantime, so David's testing is somewhat weakened by that.

This patch removes the irq_domain_add_simple() interface. This patch also drops the explicit irq_domain initialization performed by the mach-versatile code because the versatile interrupt controller already has irq_domain support built into it. This was a bug that was hanging around quietly for a while, but with the full irq_domain which actually verifies that irq_domain ranges are available it would cause the registration to fail and the system wouldn't boot. v4: Fixed number of irqs in mx5 gpio code v2: Updated to pass in host_data pointer on irq_domain allocation.

|/ | | | | | | | | | | | | | | | | It turns out that the logical CPU mapping is useful even when !CONFIG_SMP for manipulation of devices like interrupt and power controllers when running a UP kernel on a CPU other than 0. This can happen when kexecing a UP image from an SMP kernel. In the future, multi-cluster systems running AMP configurations will require something similar for mapping cluster IDs, so it makes sense to decouple this logic in preparation for this support.

Therefore, when the timer is free running it's possible for the count to wrap and the match value to match again even though a set_next_event() call hasn't been made since the last match. Workaround the lack of an interrupt enable bit by explicitly stopping the timer in the interrupt handler when the clockevent is in ONESHOT mode. This should prevent any possibility of the timer wrapping and matching more than once per set_next_event().

This is exactly what happens today with MSM timers. The same hardware is used for both the clockevent and the clocksource because the ratings of the two are the same. Fix this by registering a clockevent based on the GPT and a clocksource based on the DGT. This removes any other possible configuration (e.g. a GPT clocksource and a DGT clockevent) but that shouldn't be a big issue since we want higher precision timing than high precision scheduling interrupts.
