Arnd, Olof,
Please pull for 3.9. This is the initial infrastructure and conversion
of the GIC and VIC to use it. Several people are waiting for the irqchip
infrastructure to go in in order to convert other irqchip code over.
I've left "static asmlinkage" in on the irq handlers. There's been no
more discussion, so I think we are in agreement. If asmlinkage defines
the procedure call convention for assembly calls, then it still makes
sense to have it on a static function called thru a function pointer.
Rob

irqchip: Move ARM vic.h to include/linux/irqchip/arm-vic.h (2013-01-12 10:52:16 -0600)
----------------------------------------------------------------
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.
----------------------------------------------------------------
Rob Herring (16):
ARM: GIC: remove assembly ifdefs from gic.h
ARM: GIC: remove direct use of gic_raise_softirq
ARM: GIC: set handle_arch_irq in GIC initialization
ARM: remove mach .handle_irq for GIC users
irqchip: Move ARM GIC to drivers/irqchip
ARM: use common irqchip_init for GIC init
irqchip: Move ARM gic.h to include/linux/irqchip/arm-gic.h
ARM: VIC: shrink down vic.h
ARM: VIC: set handle_arch_irq in VIC initialization
ARM: remove mach .handle_irq for VIC users
ARM: remove unneeded vic.h includes
ARM: samsung: remove unused tick.h
irqchip: Move ARM VIC to drivers/irqchip
ARM: spear: use common irqchip_init function
ARM: picoxcell: use common irqchip_init function
irqchip: Move ARM vic.h to include/linux/irqchip/arm-vic.h
Srinidhi Kasagar (1):
ARM: mach-ux500: use SGI0 to wake up the other core
Thomas Petazzoni (3):
irqchip: add to the directories part of the IRQ subsystem in MAINTAINERS
irqchip: add basic infrastructure
arm: add set_handle_irq() to register the parent IRQ controller handler function

Ugh. This conflicts heavily with the timer cleanup from Stephen, due
to adjacent changes in the machine descriptors.
I fixed them up, but I would appreciate a second glance at them for
sanity checking.

Sorry about that. It all looks correct to me.
