Fix up mostly pretty trivial conflicts in: - arch/arm/Kconfig - arch/arm/include/asm/localtimer.h - arch/arm/kernel/Makefile - arch/arm/mach-shmobile/board-ap4evb.c - arch/arm/mach-u300/core.c - arch/arm/mm/dma-mapping.c - arch/arm/mm/proc-v7.S - arch/arm/plat-omap/Kconfig largely due to some CONFIG option renaming (ie CONFIG_PM_SLEEP -> CONFIG_ARM_CPU_SUSPEND for the arm-specific suspend code etc) and addition of NEED_MACH_MEMORY_H next to HAVE_IDE.

| | * ARM: gic, local timers: use the request_percpu_irq() interfaceMarc Zyngier2011-10-238-111/+99
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch remove the hardcoded link between local timers and PPIs, and convert the PPI users (TWD, MCT and MSM timers) to the new *_percpu_irq interface. Also some collateral cleanup (local_timer_ack() is gone, and the interrupt handler is strictly private to each driver). PPIs are now useable for more than just the local timers. Additional testing by David Brown (msm8250 and msm8660) and Shawn Guo (imx6q).

| | * ARM: gic: consolidate PPI handlingMarc Zyngier2011-10-2314-178/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | PPI handling is a bit of an odd beast. It uses its own low level handling code and is hardwired to the local timers (hence lacking a registration interface). Instead, switch the low handling to the normal SPI handling code. PPIs are handled by the handle_percpu_devid_irq flow. This also allows the removal of some duplicated code.

| | * | | ARM: switch from NO_MACH_MEMORY_H to NEED_MACH_MEMORY_HNicolas Pitre2011-10-133-41/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Given that we want the default to not have any <mach/memory.h> and given that there are now fewer cases where it is still provided than the cases where it is not at this point, this makes sense to invert the logic and just identify the exception cases. The word "need" instead of "have" was chosen to construct the config symbol so not to suggest that having a mach/memory.h file is actually a feature that one should aim for.

Any config that was actually expecting the mach-s3c2400 version was therefore producing a broken kernel binary. Not relying on any of them anymore would fix that issue.

If/when all instances of mach/memory.h are removed then this symbol could be removed. Signed-off-by: Nicolas Pitre <nicolas.pitre@linaro.org>

There is a catch though: the busyuart macro needs to know where the LSR register is which might be at a different offset depending on the hardware. Given that this macro is given only two registers and that one of them must be preserved, the trick is to always pass the LSR register address around, and deduce the base address for the THR register by masking out the LSR offset in senduart instead.
