<div class='commit-subject'>Merge branch 'rcu-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip</div><div class='commit-msg'>Pull RCU fixes from Ingo Molnar:
 "This fixes sporadic ACPI related hangs in synchronize_rcu() that were
  caused by the ACPI code mistakenly relying on an aspect of RCU that
  was neither promised to work nor reliable but which happened to work -
  until in v4.9 we changed the RCU implementation, which made the hangs
  more prominent.

  Since the mis-use of the RCU facility wasn't properly detected and
  prevented either, these fixes make the RCU side work reliably instead
  of working around the problem in the ACPI code.

  Hence the slightly larger diffstat that goes beyond the normal scope
  of RCU fixes in -rc kernels"

* 'rcu-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  rcu: Narrow early boot window of illegal synchronous grace periods
  rcu: Remove cond_resched() from Tiny synchronize_sched()
