Merge branch 'core-locking-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip

* 'core-locking-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip:
  mutex: Fix missing conditions to build mutex_spin_on_owner()
  mutex: Better control mutex adaptive spinning config
  locking, task_struct: Reduce size on TRACE_IRQFLAGS and 64bit
  locking: Use __[SPIN|RW]_LOCK_UNLOCKED in [spin|rw]_lock_init()
  locking: Remove unused prototype
  locking: Reduce ifdefs in kernel/spinlock.c
  locking: Make inlining decision Kconfig based
