From: Jan Beulich
Date: Tue Jul 19 2011 - 07:59:26 EST

This is to unify 32- and 64-bit assembly implementations and to eliminate
a (mostly theoretical) scalability problem in the rwlock logic.

1: unify rwlock assembly implementation
2: unify rwsem assembly implementation
3: fix write lock scalability 64-bit issue
