Hi Jonas,

Thanks for your submission, it looks very nice and is well split up into
readable patches. I have no doubt that you will be able to get this included
in Linux-3.1 given the high quality. I'll go through the individual patches
and comment on anything that sticks out. Please resubmit once you have
addressed all of the comments from me and other people, and take
linux-arch@xxxxxxxxxxxxxxx on Cc for the second round, because otherwise
some people may miss the patches in the daily flood.

How about including the TODO file here?

I agree that this is important to clean it all up, but it's good that you
posted the current version.

I would also suggest that you let Stephen Rothwell add your git tree to
the linux-next sources, provided that it merges cleanly with the upstream
