Hi.

Acked-by: Geoff Levand <geoffrey.levand at am.sony.com>

I tested this with PS3 and it works as expected.  I added it to my
ps3-kexec-tools.git.  With this patch mainline kexec will work
with the PS3.

I still have a work-in-progress patch started by David Woodhouse
to support building a 32 bit kexec executable for PPC64 platforms.
I don't have any definite plan to work on it though.
