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

Pull perf fixes from Ingo Molnar:
 "These are late-v3.7 pending fixes for tracing."

Fix up trivial conflict in kernel/trace/ring_buffer.c: the NULL pointer
fix clashed with the change of type of the 'ret' variable.

* 'perf-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  ring-buffer: Fix race between integrity check and readers
  ring-buffer: Fix NULL pointer if rb_set_head_page() fails
  ftrace: Clear bits properly in reset_iter_read()
