Subject: powerpc/numa: Avoid stupid uninitialized warning from gcc
From: Benjamin Herrenschmidt <benh@xxxxxxxxxxxxxxxxxxx>
commit aa709f3bc92c6daaf177cd7e3446da2ef64426c6 upstream.
Newer gcc are being a bit blind here (it's pretty obvious we don't
reach the code path using the array if we haven't initialized the
pointer) but none of that is performance critical so let's just
silence it.
