Linus,
please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/livepatching/livepatching tags/livepatching-for-5.5
to receive livepatching subsystem update.
=====================================
+ 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.
======================================
There is expected one merge conflict with ftrace tree. Both add a new
independent selftest.
