It does, indeed.  Because they are independent, we can drop the ppc64
portion for now, and we'll submit the tested changes at least before the
sparsemem merge for that arch.

I've attached the i386-only version, along with the NUMA-Q fix, which
replaces the original patch.  I can also wait until the next -mm to
ensure that it is tested properly.
