[PATCH 0/4] MCS Lock: MCS lock code cleanup and optimizations

[Tim Chen]

In this patch series, we separated out the MCS lock code which was previously embedded in the
mutex.c.  This allows for easier reuse of MCS lock in other places like rwsem and qrwlock.
We also did some micro optimizations and barrier cleanup.

This patches were previously part of the rwsem optimization patch series but now we spearate
them out.
