FUTEX_LOCK_PI2 is a new futex operation which was recently introduced into the
Linux kernel. It works exactly like FUTEX_LOCK_PI. However, it has support for
selectable clocks for timeouts. By default CLOCK_MONOTONIC is used. If
FUTEX_CLOCK_REALTIME is specified then the timeout is measured against
CLOCK_REALTIME.

This new operation addresses an inconsistency in the futex interface:
FUTEX_LOCK_PI only works with timeouts based on CLOCK_REALTIME in contrast to
all the other PI operations.

Document the FUTEX_LOCK_PI2 command.

Please drop this one.  I just found a small typo, and will add a 
Reviewed-by line received today.

Dropped.
