3.12-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dinh Nguyen <dinguyen@xxxxxxxxxx>
commit 85dc6ee1237c8a4a7742e6abab96a20389b7d682 upstream.
The read_sched_clock should return the ~value because the clock is a
countdown implementation. read_sched_clock() should be the same as
__apbt_read_clocksource().
