This typo causes the incorrect calculation of the IRQ numbers
in the ICIP2 registers.

ICIP2 is not examined during IRQ entrance, this patch add the
checking if the processor is PXA27x or later, with CoreG bits
in CPUID (Core Generation) > 1

1. PXA_IRQ_SKIP is defined to be 7 on PXA25x so that the first IRQ
starts from zero. This makes IRQ numbering inconsistent between
PXA25x and PXA27x. Remove this macro so that the same IRQ_XXXXX
definition has the same value on both PXA25x and PXA27x.
2. make IRQ_SSP3..IRQ_PWRI2C valid only if PXA27x is defined, this
avoids unintentional use of these macros on PXA25x

get_irqnr_preamble allows machines to take some action before entering the
get_irqnr_and_base loop. On iop we enable cp6 access.
arch_ret_to_user is added to the userspace return path to allow individual
architectures to take actions, like disabling coprocessor access, before
the final return to userspace.
Per Nicolas Pitre's note, there is no need to cp_wait on the return to user
as the latency to return is sufficient.

arch/arm/kernel/entry-armv.S has contained a comment suggesting
that asm/hardware.h and asm/arch/irqs.h should be moved into the
asm/arch/entry-macro.S include. So move the includes to these
two files as required.
Add missing includes (asm/hardware.h, asm/io.h) to asm/arch/system.h
includes which use those facilities, and remove asm/io.h from
kernel/process.c.
Remove other unnecessary includes from arch/arm/kernel, arch/arm/mm
and arch/arm/mach-footbridge.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
