This is release -V3 of the "lightweight robust futexes" patchset. The
patchset can also be downloaded from:

http://redhat.com/~mingo/lightweight-robust-futexes/

Changes since -V2:

Ulrich Drepper ran the code through more glibc testcases, which
unearthed a couple of bugs:

- fixed bug in the i386 and x86_64 assembly code (Ulrich Drepper)

- fixed bug in the list walking futex-wakeups (found by Ulrich Drepper)

- race fix: do not bail out in the list walk when the list_op_pending
pointer cannot be followed by the kernel - another userspace thread
may have already destroyed the mutex (and unmapped it), before this
thread had a chance to clear the field.

- cleanup: renamed list_add_pending to list_op_pending. (the field is
used for list removals too)
