[PATCH v5 0/3] locking/qrwlock: More optimizations in qrwlock

[Waiman Long <Waiman.Long@hp.com>]

v4->v5:
 - Add a new patch to rename function names to sync up to qspinlock
   naming convention.
 - Move the extended qrwlock structure to the header file as requested
   by Will Deacon so that it can also be used in the ARM's architecture
   specific code.

v3->v4:
 - Remove the unnecessary _QW_WMASK check in
   queue_read_lock_slowpath().

v2->v3:
 - Fix incorrect commit log message in patch 1.

v1->v2:
 - Add microbenchmark data for the second patch

This patch set contains 2 patches on qrwlock. The first one is to
optimize the interrupt context reader slowpath.  The second one is
to optimize the writer slowpath.
