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@xxxxxxxxxxxxxxxx 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.
