Merge tag 'gic-vic-to-irqchip' of git://sources.calxeda.com/kernel/linux into next/cleanup

From Rob Herring:

Initial irqchip init infrastructure and GIC and VIC clean-ups

This creates irqchip initialization infrastructure from Thomas
Petazzoni. The VIC and GIC irqchip code is moved to drivers/irqchips
and adapted to use the new infrastructure. All DT enabled platforms
using GIC and VIC are converted over to use the new irqchip_init.

* tag 'gic-vic-to-irqchip' of git://sources.calxeda.com/kernel/linux:
  irqchip: Move ARM vic.h to include/linux/irqchip/arm-vic.h
  ARM: picoxcell: use common irqchip_init function
  ARM: spear: use common irqchip_init function
  irqchip: Move ARM VIC to drivers/irqchip
  ARM: samsung: remove unused tick.h
  ARM: remove unneeded vic.h includes
  ARM: remove mach .handle_irq for VIC users
  ARM: VIC: set handle_arch_irq in VIC initialization
  ARM: VIC: shrink down vic.h
  irqchip: Move ARM gic.h to include/linux/irqchip/arm-gic.h
  ARM: use common irqchip_init for GIC init
  irqchip: Move ARM GIC to drivers/irqchip
  ARM: remove mach .handle_irq for GIC users
  ARM: GIC: set handle_arch_irq in GIC initialization
  ARM: GIC: remove direct use of gic_raise_softirq
  ARM: GIC: remove assembly ifdefs from gic.h
  ARM: mach-ux500: use SGI0 to wake up the other core
  arm: add set_handle_irq() to register the parent IRQ controller handler function
  irqchip: add basic infrastructure
  irqchip: add to the directories part of the IRQ subsystem in MAINTAINERS

Fixed up massive merge conflicts with the timer cleanup due to adjacent changes:
