Linus,

please pull from

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

to receive livepatching subsystem updates for 5.8.

You are going to get a minor conflict with modules tree; the correct 
resolution is documented at

	http://lore.kernel.org/r/20200508180524.6995b07e@canb.auug.org.au

Alternatively, I can just prepare a branch for you to pull with the 
conflict resolved.

Thanks.

=====
- simplifications and improvements for issues Peter Ziljstra found during 
  his previous work on W^X cleanups. This allows us to remove livepatch 
  arch-specific .klp.arch sections and add proper support for jump labels
  in patched code. Also, this patchset removes the last 
  module_disable_ro() usage in the tree. Patches from Josh Poimboeuf and 
  Peter Zijlstra
- a few other minor cleanups
