My previous attempt to fix a couple of bugs in __restore_processor_context():

5b06bbcfc2c6 ("x86/power: Fix some ordering bugs in __restore_processor_context()")

... introduced yet another bug, breaking suspend-resume.

Rather than trying to come up with a minimal fix, let's try to clean it up for real. This patch fixes quite a few things:

5b06bbcfc2c6 fixed theoretical bug; rather than porting it to stable than fixing it up, it would be better not to port it to stable in the first place or simply revert it there.

Thanks, Pavel
