Subject: [PATCH 0/5] Futex cleanups and race fix

The following series corrects several innacurate comments in the futex code as
well as reformat some of the existing comments to be mostly consistent
throughout futex.c. The final patch fixes a nasty little race in the requeue pi
code resulting in missed wakeups and hung userspace application threads.
