[PATCH] ppc64 Kconfig memory models

[Mike Kravetz <kravetz@us.ibm.com>]

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.
