<div class='commit-subject'>Merge branch 'smp-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip</div><div class='commit-msg'>Pull SMP hotplug update from Thomas Gleixner:
 "This contains a trivial typo fix and an extension to the core code for
  dynamically allocating states in the prepare stage.

  The extension is necessary right now because we need a proper way to
  unbreak LTTNG, which iscurrently non functional due to the removal of
  the notifiers. Surely it's out of tree, but it's widely used by
  distros.

  The simple solution would have been to reserve a state for LTTNG, but
  I'm not fond about unused crap in the kernel and the dynamic range,
  which we admittedly should have done right away, allows us to remove
  quite some of the hardcoded states, i.e. those which have no ordering
  requirements. So doing the right thing now is better than having an
  smaller intermediate solution which needs to be reworked anyway"
