Linus,

please pull from

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

to receive livepatching subsystem updates for 5.1 merge window:

=====
- support for something we call 'atomic replace', and allows for much
  better handling of cumulative patches (which is something very useful
  for distros), from Jason Baron with help of Petr Mladek and Jason Baron.
- improvement of handling of tasks blocking finalization, from Miroslav 
  Benes
- update of MAINTAINERS file to reflect move towards group maintainership
=====

Thanks.
