[PATCH] ppc64: POWER 4 fails to boot with NUMA
If CONFIG_NUMA is set, some POWER 4 systems will fail to boot. This is
because of special processing needed to handle invalid node IDs (0xffff) on
POWER 4. My previous patch to handle memory 'holes' within nodes forgot to
add this special case for POWER 4 in one place.
In reality, I'm not sure that configuring the kernel for NUMA on POWER 4 makes
much sense. Are there POWER 4 based systems with NUMA characteristics that
are presented by the firmware? But, distros want one kernel for all systems
so NUMA is on by default in their kernels. The patch handles those cases.
