Subject: [PATCH] ppc64: cut down paca footprint

The paca currently contains an iseries only structure which is quite large
(~1kB).  The following patch removes this overhead on pseries and g5
kernels.

Since the paca is no longer required to be page aligned, remove it from the
page aligned section.
