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

Pull livepatching fixes from Jiri Kosina:

 - symbol lookup locking fix, from Miroslav Benes

 - error handling improvements in case of failure of the module coming
   notifier, from Minfei Huang

 - we were too pessimistic when kASLR has been enabled on x86 and were
   dropping address hints on the floor unnecessarily in such case.  Fix
   from Jiri Kosina

 - a few other small fixes and cleanups
