3.1.0-ck1, BFS 0.414

I finally found enough time to sync up BFS with the latest 3.1.0 linux kernel. In keeping with the fact that there are some changes to support new scheduler features in linux-3.1, and the general code churn that happens on every release, the version number is updated from the last 0.413 release but from the user perspective it should behave identically. There were some build fixes pending and one bug involving displayed hard interrupt usage that were fixed. Overall most users should notice no significant change.

Apply to linux-3.1.x:
3.1-sched-bfs-414.patch

Closely following on with syncing up with the latest kernel is an updated -ck kernel which is almost identical, apart from relaxing the swappiness from 0 to 10. Some very low ram users reported the virtual memory subsystem tried so hard to not swap anything at 0 that they experienced stalls while the VM twiddled its thumbs screwing around so I've relaxed the value to 10 which avoids these stalls and should still be quite aggressive at avoiding swapping.

Apart from that the -ck patch is a resync from the last 3.0.0-ck1 release:

3.1.0-ck1

With the recent kernel.org hacking it has become a lot harder to get a kernel.org account and as I would have great difficulty getting a gpg key personally signed by any other kernel developer in my area it could be a while before I can set up an account there again. So I've decided to just use my own storage once more instead of putting it on kernel.org. Unfortunately I don't have quite a few of the older -ck kernels since I never bothered to upload them there. I foolishly thought that kernel.org storage would be permanent cloud storage for them so I don't even have a copy of many of them. If someone has archived the 2.6 -ck patches, or has an old mirror of kernel.org please forward them on to me.

Enjoy!

EDIT: A few bugs are showing up in this latest BFS release, and I'm currently accumulating fixes fort them and putting them in the directory listed above for ck1. There will be a ck2 soon to follow with all the fixes.
