1c9d3df5e8 [ARM] 4078/1: Fix ARM copypage cache coherency problems
If PG_dcache_dirty is set for a page, we need to flush the source page
before performing any copypage operation using a different virtual address.

This fixes the copypage implementations for XScale, StrongARM and ARMv6.

This patch fixes segmentation faults seen in the dynamic linker under
the usage patterns in glibc 2.4/2.5.

ad1ae2fe7f [ARM] Unuse another Linux PTE bit
L_PTE_ASID is not really required to be stored in every PTE, since we
can identify it via the address passed to set_pte_at().  So, create
set_pte_ext() which takes the address of the PTE to set, the Linux
PTE value, and the additional CPU PTE bits which aren't encoded in
the Linux PTE value.

1b2e2b73b4 [ARM] Cleanup arch/arm/mm a little
Move top_pmd into arch/arm/mm/mm.h - nothing outside arch/arm/mm
references it.

Move the repeated definition of TOP_PTE into mm/mm.h, as well as
a few function prototypes.

b4c2803ca8 [ARM] Make v6 copypage function static and cleanup pgprots
We know what pgprot we're going to use, so don't #define it.  Also,
since we select the nonaliasing/aliasing copypage implementation at
run time, there's no point having it globally visible.

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!
