This a set of misc ppc arch specific code improvements/optimizations.
This version of series extended improvements to p7 and p8 alongwith
additional minor improvements.

Since patch 7/7 of v2 series have been picked by Aditya in his patchset
for P11 support, I have excluded that patch in this series and based on
top of his v6 series which contains the required patch as 1/5.
Based on: <[e-mail]>
