Allright, I won't resend the whole series, I can just pickup my previous
patch. Takashi, Bjorn, Dave, this series covers your 3 areas of
maintainership, how do you want to proceed ? I'm happy to merge the
whole lot via powerpc ASAP (since it's all CC'ed stable) if you guys
send me the appropriate acks, otherwise, let me know.

Cheers,
Ben.
