[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.
