Hmm, I expect that I've inadvertently ended up basing my patches on a branch
that Russell has rebased. I mentioned this on the list at the time:

http://lists.infradead.org/pipermail/linux-arm-kernel/2011-September/063729.html

It looks like both of the branches [cpu-mapping and debug-ll] may be out of
date now. I agree that fixing up the conflicts isn't the way to go here, but
I'm unsure what to use as my base. I depend on patches that aren't in
Russell's devel-stable branch but are in his for-next branch.

The only things I can think of are either:

 - Wait until everything has settled down, then rebase onto Russell's
   for-linus branch. This has the disadvantage that conflicts and build
   breakages won't be detected until very late.

 - Wait until the dependencies are in mainline, then rebase against that.
   Disadvantage is that it then takes twice as long to get code upstream.

 - Send another pull request against an unstable branch and hope it doesn't
   change. Disadvantage being that we have to keep repeating pull requests
   against a moving target.

I'm not especially fond of any of those though...

Do you have any other ideas?

Cheers,

Will
