If CONFIG_NUMA is set, some POWER 4 systems will fail to boot. This is
because of special processing needed to handle invalid node IDs (0xffff) on
POWER 4. My previous patch to handle memory 'holes' within nodes forgot to
add this special case for POWER 4 in one place.
In reality, I'm not sure that configuring the kernel for NUMA on POWER 4 makes
much sense. Are there POWER 4 based systems with NUMA characteristics that
are presented by the firmware? But, distros want one kernel for all systems
so NUMA is on by default in their kernels. The patch handles those cases.

Provide hooks for PPC64 to allow memory models to be informed of installed
memory areas. This allows SPARSEMEM to instantiate mem_map for the populated
areas.

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!
