hm, actually - the stackprotector impact is getting quite nasty. So i 
think we are better off by merging the stackprotector fixes into 
core/percpu, and then rebasing these commits on top of that. I pushed out 
a new core/percpu branch with that done - and stackprotector works in that 
lineup.

Would you mind to redo these commits on top of that? I tried the conflict 
resolution but it looks quite complex and non-obvious - it would be 
cleaner to have it this way.
