Yup.

The memory remove code for powerpc/pseries should call remove_memory()

Hi Linus !
So here's my next branch for powerpc. A bit late as I was on vacation
last week. It's mostly the same stuff that was in next already, I just
added two patches today which are the wiring up of lockref for powerpc,
which for some reason fell through the cracks last time and is trivial.

This is the patch that I had sent after -rc8 and which we decided
to wait before merging. It's based on a different tree than my

my -next is based on -rc1) so I left it as a separate branch for
