Merge branches 'perf-urgent-for-linus' and 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull perf and timer fixes from Ingo Molnar:
 "Two small perf fixes:
   - kernel side context leak fix
   - tooling crash fix

  And two clocksource driver fixes"

* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  perf: Fix context leak in put_event()
  perf annotate: Fix fallback to unparsed disassembler line

* 'timers-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  clockevents: sun5i: Fix setup_irq init sequence
  clocksource: efm32: Fix a NULL pointer dereference
