ARM: delete struct sys_timer Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.

ARM: EXYNOS: to declare static for mach-exynos/common.c According to commit cc511b8d84d8 ("ARM: 7257/1: EXYNOS: introduce arch/arm/mach-exynos/common.[ch]"), we don't need to declare extern for exynos4_map_io(), exynos4_init_clocks(), exynos4_init_uarts(), and exynos_init(). And the exynos4210_register_clocks() and exynos4212_register_clocks depend on each SoC not ARCH_EXYNOS4. So this patch fixed above. Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>

ARM: exynos: move exynos4210-combiner to drivers/irqchip Exynos boot is broken with commit 0529e315 (ARM: use common irqchip_init for GIC init). This commit split the irqchip initialization into 2 calls to of_irq_init. This does not work because of_irq_init requires interrupt parents to be in the match list. Rather than reverting exynos changes, make it do the proper thing by using IRQCHIP_DECLARE. This requires moving the combiner code to drivers/irqchip.
