Pull locking fixes from Thomas Gleixner: "The locking department delivers: - A rather large and intrusive bundle of fixes to address serious performance regressions introduced by the new rwsem / mcs technology. Simpler solutions have been discussed, but they would have been ugly bandaids with more risk than doing the right thing. - Make the rwsem spin on owner technology opt-in for architectures and enable it only on the known to work ones. - A few fixes to the lockdep userspace library" * 'locking-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: locking/rwsem: Add CONFIG_RWSEM_SPIN_ON_OWNER locking/mutex: Disable optimistic spinning on some architectures locking/rwsem: Reduce the size of struct rw_semaphore locking/rwsem: Rename 'activity' to 'count' locking/spinlocks/mcs: Micro-optimize osq_unlock() locking/spinlocks/mcs: Introduce and use init macro and function for osq locks locking/spinlocks/mcs: Convert osq lock to atomic_t to reduce overhead locking/spinlocks/mcs: Rename optimistic_spin_queue() to optimistic_spin_node() locking/rwsem: Allow conservative optimistic spinning when readers have lock tools/liblockdep: Account for bitfield changes in lockdeps lock_acquire tools/liblockdep: Remove debug print left over from development tools/liblockdep: Fix comparison of a boolean value with a value of 2

tools/liblockdep: Account for bitfield changes in lockdeps lock_acquire

2014-07-07T16:20:16Z

Commit fb9edbe984 shortened held_lock->check from a 2-bit field to a 1-bit field. Make liblockdep compatible with the new definition by passing check=1 to lock_acquire() calls, rather than the old value check=2 (which inadvertently disabled checks by overflowing to 0). Without this fix, several of the test cases in liblockdep run_tests.sh were failing. Signed-off-by: S. Lockwood-Childs Signed-off-by: Sasha Levin

tools/liblockdep: Remove debug print left over from development

2014-07-07T16:14:27Z

Remove a debug print in init_preload() which was left over from development and isn't usefull at all currently. It was also causing false positive test results. Reported-by: S. Lockwood-Childs Signed-off-by: Sasha Levin

tools/liblockdep: Fix comparison of a boolean value with a value of 2

2014-07-07T16:02:21Z

Comparison of a boolean value (!__init_state) with a value of 2 (done) as currently happens in the code is unlikely to succeed and causes repeated initialization of the pthread function pointers. Instead, remove boolean comparison so that we would initialize said function pointers only once.

tools/testing/selftests/ipc/msgque.c: improve error handling when not running as root

2014-07-03T16:21:54Z

The test fails in the middle when it is not run as root while accessing /proc/sys/kernel/msg_next_id. Changed it to check for root at the beginning of the test and exit if not root.

tools: memory-hotplug fix unexpected operator error

2014-07-03T16:21:53Z

on-off-test uses "$UID != 0" to test for root, but $UID is a construct specific to bash. Using /bin/sh that isn't bash results in the following error (due to the "$UID" part expanding to nothing): ./on-off-test.sh: 9: [: !=: unexpected operator Change Makefile to use bash instead.
