Subject: [PATCHSET tip:x86/mm] x86-32, NUMA: Clean up alloc_remap

Hello,

This patchset cleans up remap allocator in preparation for 32/64bit
NUMA unification.  After the patchset, remap allocator initialization
is separate from the rest of NUMA initializaiton.  In the process,
several bugs are fixed and boot is made less verbose.

This patchset contains the following fourteen patches.  Please note
that x86/urgent needs to be pulled into x86/mm for 32bit NUMA to work
at all (765af22da8 "x86-32, NUMA: Fix ACPI NUMA init broken by recent
x86-64 change").
