The advent of big.LITTLE ARM platforms requires the kernel to be able
to identify the MIDRs of all online CPUs upon request. MIDRs are stashed
at boot time so that kernel subsystems can detect the MIDR of online CPUs
by simply retrieving per-CPU data updated by all booted CPUs.

The file arch/arm/include/asm/cpu.h needs to include 'linux/cpu.h' to
meet its dependency. Otherwise when using "struct cpuinfo_arm" and
including just 'asm/cpu.h' throws below error -
	arch/arm/include/asm/cpu.h:16: error: field 'cpu' has incomplete type

To fix this  otherway, one can also include both linux/cpu.h and
asm/cpu.h but it shoudn't be that way.  So this patch fixes this by
including the linux/cpu.h in asm/cpu.h, so that including alone
asm/cpu.h is enough.

Move platform independent header files to arch/arm/include/asm, leaving
those in asm/arch* and asm/plat* alone.

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!
