[PATCH] reorganize x86-64 NUMA and DISCONTIGMEM config options
In order to use the alternative sparsemem implmentation for NUMA kernels, we need to reorganize the config options. This patch effectively abstracts out the CONFIG_DISCONTIGMEM options to CONFIG_NUMA in most cases. Thus, the discontigmem implementation may be employed as always, but the sparsemem implementation may be used alternatively.
