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