Patch from Catalin Marinas

Since ARM1176, the CPU ID format has changed and it will also be used for
future ARM architectures.

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.

glibc expects to count lines beginning with "processor" to determine
the number of processors, not lines beginning with "Processor".  So,
give glibc the format it expects.

We don't want to call dump_cpu_info() from cpu_init() after boot since
it produces a lot of unnecessary noise - since cpu_init() gets called
on resume and hotplug cpu insertion events.

Patch from Catalin Marinas

The compiler allocates r14 for the stk variable in the __asm__ directive.
This is a shadowed register and gets changed when the mode is changed,
causing random values in the SP register. The patch adds a clobber for
the r14 register.

Ensure that meminfo.bank[] array contains page-aligned start/size
information.

We need to re-initialise the stack pointers for undefined, IRQ
and abort mode handlers whenever we resume.

The current vector entry system does not allow for SMP.  In
order to work around this, we need to eliminate our reliance
on the fixed save areas, which breaks the way we enable
alignment traps.  This patch changes the way we handle the
save areas such that we can have one per CPU.

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!
