[PATCH] ppc64: Make numa=off command line argument work again
Mike's patch "ppc64: NUMA memory fixup (another try)" broke the
numa code when "numa=off" is specified on the kernel command line.
The fix is to pretend everything is in node 0 when numa is disabled.
Boot tested on pSeries LPAR with numa=off and numa=debug (ie. on).
