This is a patch series from Shawn Guo that moves from individual

a platform's late initcalls.
This cleanup is a step in the move towards multiplatform kernels since
it would reduce the need to check for compatible platforms in each and
every initcall.

Tied to both the Emma Mobile EV2 and the KZM9D board
due to the need to switch on board in platsmp.c and
the newly introduced need for static mappings.
The static mappings are needed to allow hardware

After the merge of the above commit it has been impossible to boot
sh73a0 based SoCs with SMP enabled and CONFIG_HAVE_ARM_TWD=y. The
kernel crashes at smp_init_cpus() timing which is before the console
has been initialized, so to the user this looks like a kernel lock up
without any particular error message.

Update mach-shmobile to use 0x3400 as INTCS_VECT_BASE.
Since the ARM architecture a little while back added support
for 10 bit irqs we can now undo the previously merged commit
9b7c23adb3 and use 0x3400 as
INTCS vector base.
This change is necessary to avoid overlapping of interrupt
ranges so separate IRQ domains can be used for different INTC
instances. Without this fix the vectors used by various INTC
instances are overlapping on for instance sh7372 which works
at the moment but breaks upcoming IRQ domain support.

Add INTC_IRQ_PINS_16H to allow broken out support of the
the high 16 external interrupt pins. On SoCs with 32 external
interrupt pins the interrupt vectors for the low 16 and the
high 16 interrupt pins are sparesly populated. The low 16 are
at 0x0200 and high 16 are at 0x3200 which with current macros
results in a separation of 384 linux interrupts. This sparse
population makes it unsuitable with a single IRQ domain to
cover the full IRQ range, so this macro breaks out the 32 pins
into two separate 16 bit controllers to allow two independent
INTC instances with two separate IRQ domains.

Merge tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system
Pull "Disintegrate and delete asm/system.h" from David Howells:
"Here are a bunch of patches to disintegrate asm/system.h into a set of
separate bits to relieve the problem of circular inclusion
dependencies.
I've built all the working defconfigs from all the arches that I can
and made sure that they don't break.
The reason for these patches is that I recently encountered a circular
dependency problem that came about when I produced some patches to
optimise get_order() by rewriting it to use ilog2().
This uses bitops - and on the SH arch asm/bitops.h drags in
asm-generic/get_order.h by a circuituous route involving asm/system.h.
The main difficulty seems to be asm/system.h. It holds a number of
low level bits with no/few dependencies that are commonly used (eg.
memory barriers) and a number of bits with more dependencies that
aren't used in many places (eg. switch_to()).
These patches break asm/system.h up into the following core pieces:
(1) asm/barrier.h
Move memory barriers here. This already done for MIPS and Alpha.
(2) asm/switch_to.h
Move switch_to() and related stuff here.
(3) asm/exec.h
Move arch_align_stack() here. Other process execution related bits
could perhaps go here from asm/processor.h.
(4) asm/cmpxchg.h
Move xchg() and cmpxchg() here as they're full word atomic ops and
frequently used by atomic_xchg() and atomic_cmpxchg().
(5) asm/bug.h
Move die() and related bits.
(6) asm/auxvec.h
Move AT_VECTOR_SIZE_ARCH here.
Other arch headers are created as needed on a per-arch basis."
Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that. We'll find out anything that got broken and fix it..
