Ping? We are planning to remove support for __get_cpu_var in the
3.19 merge period. I can move the definition for __get_cpu_var into the
powerpc per cpu definition instead if we cannot get this merged?

Yes, yes, I know, we should merge that, Michael, can you still throw
that in ?

For 3.18, nah. We didn't even see it until after the merge window had closed.

No, we did see it a long time ago Michael, we just forgot about it. We
should put it in, everybody else has their equivalent.

I realise they're all fairly simple translations, but it's too big and too easy
for one of them to be wrong.

I'm happy to put it in a topic branch for 3.19, or move the definition or
whatever, your choice Christoph.

But then we'll have a tricky sync needed to make sure the removal of
__get_cpu_var() doesn't get into Linus tree before this. Unless we just
ack the whole lot and let Christoph carry it in the same branch where
the removal is.

Ben.
