Subject: arm: add set_handle_irq() to register the parent IRQ controller
 handler function

In order to allow irqchip drivers to register their IRQ handling
function as the parent IRQ controller handler function, we provide a
convenience function. This will avoid poking directly into the global
handle_arch_irq variable.

Suggested by Arnd Bergmann.

Subject: ARM: mach-ux500: use SGI0 to wake up the other core

The commit 7d28e3eaa1a8e951251b942e7220f97114bd73b9
("ARM: ux500: wake secondary cpu via resched") makes use
of schedule IPI to wake up the secondary core which seems
incorrect. Rather use SGI0.

Subject: ARM: GIC: remove direct use of gic_raise_softirq

In preparation of moving gic code to drivers/irqchip, remove the direct
platform dependencies on gic_raise_softirq. Move the setup of
smp_cross_call into the gic code and use arch_send_wakeup_ipi_mask
function to trigger wake-up IPIs.

Subject: ARM: GIC: set handle_arch_irq in GIC initialization

Set handle_arch_irq to gic_handle_irq. Only the first GIC initialized can
setup the handler.

Subject: ARM: remove mach .handle_irq for GIC users

Now that the GIC initialization sets up the handle_arch_irq pointer, we
can remove it for all machines and make it static.

From 81243e444c6e9d1625073e4a3d3bc244c8a545f0 Mon Sep 17 00:00:00 2001
From: Rob Herring <rob.herring@calxeda.com>
Date: Tue, 20 Nov 2012 21:21:40 -0600
Subject: irqchip: Move ARM GIC to drivers/irqchip

Now that we have drivers/irqchip, move GIC irqchip to drivers/irqchip. This
is necessary to share the GIC with arm and arm64.

From 520f7bd73354f003a9a59937b28e4903d985c420 Mon Sep 17 00:00:00 2001
From: Rob Herring <rob.herring@calxeda.com>
Date: Thu, 27 Dec 2012 13:10:24 -0600
Subject: irqchip: Move ARM gic.h to include/linux/irqchip/arm-gic.h

Now that we have GIC moved to drivers/irqchip and all GIC DT init for
platforms using irqchip_init, move gic.h and update the remaining
includes.

Subject: ARM: VIC: shrink down vic.h

Move all register defines except VIC_INT_ENABLE and VIC_INT_ENABLE_CLEAR
which are used by Samsung.

With multi irq handler, vic.h is not included in assembly any more, so
we can remove the assembly ifdefs.

Subject: ARM: remove mach .handle_irq for VIC users

Now that the VIC initialization sets up the handle_arch_irq pointer, we
can remove it for all machines and make it static. Move vic_handle_irq
to avoid a forward declaration.

Subject: irqchip: Move ARM vic.h to include/linux/irqchip/arm-vic.h

Now that we have VIC moved to drivers/irqchip and all VIC DT init for
platforms using irqchip_init, move gic.h and update the remaining
includes.
