Merge branch 'irqchip-consolidation' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into devel-stable
Conflicts:
arch/arm/mach-omap2/board-4430sdp.c
arch/arm/mach-omap2/board-omap4panda.c
arch/arm/mach-omap2/include/mach/omap4-common.h
arch/arm/plat-omap/include/plat/irqs.h
The changes to omap4-common.h were moved to arch/arm/mach-omap2/common.h
and the other trivial conflicts resolved. The now empty ifdef in irqs.h
was also eliminated.
