Subject[PATCH 0/6] sched, wait: Collapse __wait_event macros -v4
While poking at the cpu hotplug implementation I had a desire to use
wait_event() with schedule_preempt_disabled() and found the rediculous
amount of duplication in linux/wait.h.

These patches attempt to cure some of this while also making it
'trivial' to generate new variants.

Compile and boot tested on x86_64.

Changes since -v3:
- added LKML to the CC (D'0h!!)
- introduced ___wait_cond_timeout() to avoid double evalutation of 'condition'

Changes since -v2:
- removed ___wait_cmd_lock_irq(), ___wait_cmd_lock_irq_timo()
- renamed ___wait_cmd_test_timeout() to ___wait_test_timeout()
- renamed ___wait_cmd_schedule_timeout() to ___wait_sched_timeout()
- fixed schedule_timeout() invocations in patch 6; don't restart a
schedule_timeout() at the total timeout; rather continue where we
left off for a total fixed timeout.
- use 'long' return type for ___wait_event() so that timeout values
for schedule_timeout() fit.
- fix wait_event_interruptible_lock_irq_timeout() and use long return type.
