[GIT PULL] livepatching for 4.15

[Jiri Kosina]

Linus,

please pull from

  git://git.kernel.org/pub/scm/linux/kernel/git/jikos/livepatching.git for-linus

to receive the following updates to livepatching infrastructure for 4.15:

=====
- shadow variables support, allowing livepatches to associate new "shadow" 
  fields to existing data structures, from Joe Lawrence
- pre/post patch callbacks API, allowing livepatch writers to register 
  callbacks to be called before and after patch application, from Joe 
  Lawrence
=====

Thanks.
