[PATCH] ppc64: Kconfig memory models

This patch changes some of the default behavior in the ppc64 Kconfig file
that was recently changed/added to 2.6.12-rc2-mm1 by Dave Hansen in
preparation for SPARSEMEM.  Patch allows the display of both FLAT and
DISCONTIG models on pseries.  As before, default is DISCONTIG for SMP and
PSERIES and FLAT for others.
