Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/livepatching

Browse Source 
Pull livepatching updates from Jiri Kosina:

 - handle 'infinitely'-long sleeping tasks, from Miroslav Benes

 - remove 'immediate' feature, as it turns out it doesn't provide the
   originally expected semantics, and brings more issues than value

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/livepatching:
  livepatch: add locking to force and signal functions
  livepatch: Remove immediate feature
  livepatch: force transition to finish
  livepatch: send a fake signal to all blocking tasks
