So, the reverts are on the fixes-next branch of the linux-pm.git tree that you
can access at

http://git.kernel.org/cgit/linux/kernel/git/rafael/linux-pm.git/log/?h=fixes-next

However, they are not simple reverts as we've had some non-trivial changes on
top of those commits already, so I'd appreciate it a lot if somebody could
double check if I didn't break anything in them.

They are based on top of my master branch for now, but I'll rebase them on
3.11-rc3 when it's out.

Thanks,
Rafael
