Patch from Paul Gortmaker

Some folks here at Wind River asked me if I'd push this out
so that the value was generally agreed upon in advance by
all folks interested in working with iWMMXt.  Seems simple
enough...

On some CPUs, bit 4 of section mappings means "update the
cache when written to".  On others, this bit is required to
be one, and others it's required to be zero.  Finally, on
ARMv6 and above, setting it turns on "no execute" and prevents
speculative prefetches.

With all these combinations, no one value fits all CPUs, so we
have to pick a value depending on the CPU type, and the area
we're mapping.

Patch from Uwe Zeisberger

The symbol is only used in arch/arm/kernel/head-common.S.  This in turn
is included from arch/arm/kernel/head.S and arch/arm/kernel/head-nommu.S
which include asm-offsets.h .

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!
