Merge branch 'core-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull locking fixes from Ingo Molnar: "Two fixes from lockdep coverage of seqlocks, which fix deadlocks on lockdep-enabled ARM systems" * 'core-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: sched_clock: Disable seqlock lockdep usage in sched_clock() seqlock: Use raw_ prefix instead of _no_lockdep
