arch/arm/kernel/entry-armv.S has contained a comment suggesting that asm/hardware.h and asm/arch/irqs.h should be moved into the asm/arch/entry-macro.S include. So move the includes to these two files as required. Add missing includes (asm/hardware.h, asm/io.h) to asm/arch/system.h includes which use those facilities, and remove asm/io.h from kernel/process.c. Remove other unnecessary includes from arch/arm/kernel, arch/arm/mm and arch/arm/mach-footbridge. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
