Subject: [PATCH] x86-64, NUMA: Remove %NULL @nodeids handling from
 compute_hash_shift()

numa_emulation() called compute_hash_shift() with %NULL @nodeids which
meant identity mapping between index and nodeid.  Make
numa_emulation() build identity array and drop %NULL @nodeids handling
from populate_memnodemap() and thus from compute_hash_shift().  This
is to prepare for transition to using memblks instead.
