Notes: - arc asm/atomic.h is a bit of a mess after the eznps merge, I would recommend a restructure or split of that file, but could not find the will to do it. - arc, metag and tile could convert to _relaxed.Yes that was bothering me too. The split is indeed in order. However good news is even w/o it I have decent cleanup as all the backoff retry code can now be removed. The hardware guys did their foo and production RTL with latest h/w release doesn't suffer from the scond livelock problem. I'd disabled the config option for some time and now the code can be removed as well. What's ur merge plan - are u going to rebase/respin once more so I can push those updates to Linus for 4.7-rc2. Or you could carry those ARC patches in ur tree - ahead of ur series. I'd much rather prefer the revert / cleanup before adding new code which extends the back off code only to be deleted later.
I was hoping to get these into tip for v4.8, I can rebase on whatever changes you make in v4.7 no problem.
