Merge branch 'for-linus-merged' of master.kernel.org:/home/rmk/linux-2.6-arm
* 'for-linus-merged' of master.kernel.org:/home/rmk/linux-2.6-arm: [ARM] 5177/1: arm/mach-sa1100/Makefile: remove CONFIG_SA1100_USB [ARM] 5166/1: magician: add MAINTAINERS entry [ARM] fix pnx4008 build errors [ARM] Fix SMP booting with non-zero PHYS_OFFSET [ARM] 5185/1: Fix spi num_chipselect for lubbock [ARM] Move include/asm-arm/arch-* to arch/arm/*/include/mach [ARM] Add support for arch/arm/mach-*/include and arch/arm/plat-*/include [ARM] Remove asm/hardware.h, use asm/arch/hardware.h instead [ARM] Eliminate useless includes of asm/mach-types.h [ARM] Fix circular include dependency with IRQ headers avr32: Use <mach/foo.h> instead of <asm/arch/foo.h> avr32: Introduce arch/avr32/mach-*/include/mach avr32: Move include/asm-avr32 to arch/avr32/include/asm [ARM] sa1100_wdt: use reset_status to remember watchdog reset status [ARM] pxa: introduce reset_status and clear_reset_status for driver's usage [ARM] pxa: introduce reset.h for reset specific header information
