Linux v2.5.39

[Linus Torvalds]

Changes all over the map.

The most noticeable one may well be the new and much improved elevator by 
Jens Axboe, this one makes a big difference at least to me.

And Andrew found a nasty SMP deadlock on the tasklist lock.

And Ingo's been busy again, fixing some more threading issues he found 
(including the much-talked-about futex thing).

Other stuff all over the map: USB, JFS, XFS, networking, debugging etc.
