BFS 0.441, 3.11-ck1

Announcing a resync and update of the BFS CPU scheduler for linux-3.11

BFS by itself:
3.11-sched-bfs-441.patch

Full -ck1 patchset including separate patches:
3.11-ck1

Apart from the usual resync to keep up with the mainline churn, there are a few additions from BFS 0.440. A number of changes dealing with wake lists as done by mainline were added that were missing from the previous code. There is a good chance that these were responsible for a large proportion of the suspend/resume issues people were having with BFS post linux 3.8. Of course I can't guarantee that all issues have been resolved, but it has been far more stable in my testing so far.

The other significant change is to check for throttled CPUs when choosing an idle CPU to move a process to, which should impact the behaviour and possibly throughput when using a scaling CPU governor, such as ondemand.

Those of you still using the evil proprietary Nvidia binary driver (as I still do) will encounter some issues and will need to use a patched pre-release driver from them if you build it yourself, until they release a new driver.

That is all for now.

Enjoy!
