Merge tag 'livepatching-for-5.5' of git://git.kernel.org/pub/scm/linux/kernel/git/livepatching/livepatching
Pull livepatching updates from Petr Mladek:
- New API to track system state changes done be livepatch callbacks. It
helps to maintain compatibility between livepatches.
- Update Kconfig help text. ORC is another reliable unwinder.
- Disable generic selftest timeout. Livepatch selftests have their own
per-operation fine-grained timeouts.
