Add a handler for the VIC that is suitable for MULTI_IRQ_HANDLER
platforms. This can replace the ASM entry macros for platforms that use
the VIC.v4: - rebase ontop of move __exception and friends to
asm/exception.h
- rework polling loop to handle as many irqs as possible in one go
v3: - simplify irq handling loop as suggested by Grant
- service interrupts from msb->lsb order
v2: - allow the handler be used for !CONFIG_OF
- use irq_domain_to_irq()Cc: Rob Herring

This adds a device tree binding for the VIC based on the of_irq_init()
support. This adds an irqdomain to the vic and always registers all
vics in the static vic array rather than for pm only to keep track of
the irq domain. struct irq_data::hwirq is used where appropriate rather
than runtime masking.v3: - include linux/export.h for THIS_MODULE
v2: - use irq_domain_simple_ops
- remove stub implementation of vic_of_init for !CONFIG_OF
- Make VIC select IRQ_DOMAINReviewed-by: Rob Herring

Convert the omap2plus platforms to be using CONFIG_MULTI_IRQ_HANDLER.
Each machine is modified to provide either omap2_intc_handle_irq(),
omap3_intc_handle_irq() or gic_handle_irq().This allows for a major cleanup, removing the MULTI_OMAP setup
from the interrupt path.Tested on both Panda and IGEPv2 (single kernel image)

Provide the OMAP2/3 IRQ code with low level handlers that can be used
by platforms using CONFIG_MULTI_IRQ_HANDLER. Though the handlers are
written in C, the compiled code looks very similar to its assembly
counterpart (at least with my gcc 4.4.1).Tested-by: Tony Lindgren

Even when CONFIG_MULTI_IRQ_HANDLER is selected, the core code
requires the arch_irq_handler_default macro to be defined as
a fallback.It turns out nobody is using that particular feature as both PXA
and shmobile have all their machine descriptors populated with
the interrupt handler, leaving unused code (or empty macros) in
their entry-macro.S file just to be able to compile entry-armv.S.Make CONFIG_MULTI_IRQ_HANDLER exclusive wrt arch_irq_handler_default,
which allows to remove one test from the hot path. Also cleanup both
PXA and shmobile entry-macro.S.Cc: Paul Mundt

The GIC support code is heavily using the fact that hardware
implementations are exposing banked registers. Unfortunately, it
looks like at least one GIC implementation (EXYNOS) offers both
the distributor and the CPU interfaces at different addresses,
depending on the CPU.This problem is solved by allowing the distributor and CPU interface
addresses to be per-cpu variables for the platforms that require it.
The EXYNOS code is updated not to mess with the GIC internals while
handling interrupts, and struct gic_chip_data is back to being private.
The DT binding for the gic is updated to allow an optional "cpu-offset"
value, which is used to compute the various base addresses.Finally, a new config option (GIC_NON_BANKED) is used to control this
feature, so the overhead is only present on kernels compiled with
support for EXYNOS.Tested on Origen (EXYNOS4) and Panda (OMAP4).

Commit 8dc7a9c84 ("blackfin: Add export.h to files using
EXPORT_SYMBOL/THIS_MODULE") inserted some of the include statements into
sections protected by an unrelated #if CONFIG_... statement. This can cause,
depending on the configuration used, warnings like this one:arch/blackfin/mach-bf537/boards/stamp.c:2940: warning: data definition has no type or storage class
arch/blackfin/mach-bf537/boards/stamp.c:2940: warning: type defaults to ‘int’ in declaration of ‘EXPORT_SYMBOL’
arch/blackfin/mach-bf537/boards/stamp.c:2940: warning: parameter names (without types) in function declarationThis patch fixes it by moving the includes out of the #if protected sections.
