Subject: [PATCHSET x86/numa] x86-64, NUMA: bring sanity to NUMA config/emulation

Hello,

This patchset is combination of bring-sanity-to-NUMA-configuration[1]
and bring-sanity-to-NUMA-emulation[2] patchsets.  The patchsets have
been rebased on the current tip/x86/mm[3].

Most conflicts are from the addition of init_memory_mapping_high() by
commit 1411e0ec31 (x86-64, numa: Put pgtable to local node memory).
The patches in this series have been updated to carry the calls around
but the changes are all straight forward.

This patchset contains the following 33 patches
