# Merge: a789d5f8a99a f55d9895884b
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Thu Jun 4 11:13:03 2020 -0700
# 
#     Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/livepatching/livepatching
#     
#     Pull livepatching updates from Jiri Kosina:
#     
#      - 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
#
