[PATCH 0/2] sched: Introduce rcuwait

Hi,

Here's an updated version of the pcpu rwsem writer wait/wake changes
with the abstractions wanted by Oleg. Patch 1 adds rcuwait (for a lack
of better name), and patch 2 trivially makes use of it.

Has survived torture testing, which is actually very handy in this case
particularly dealing with equal amount of reader and writer threads.

Thanks.
