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.

Sorry, I merged it and forgot to reply. Patch applied (And a minor
inconsistency fixed: s/5.14.0/5.14/ ; All references to kernel 5
versions have 2 fields in the manual pages). And some other minor fixes
too.

Thanks for the review. I'll add that line.
