Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/livepatching
Pull livepatching updates from Jiri Kosina:
- remove of our own implementation of architecture-specific relocation
code and leveraging existing code in the module loader to perform
arch-dependent work, from Jessica Yu.
The relevant patches have been acked by Rusty (for module.c) and
Heiko (for s390).
- live patching support for ppc64le, which is a joint work of Michael
Ellerman and Torsten Duwe. This is coming from topic branch that is
share between livepatching.git and ppc tree.
- addition of livepatching documentation from Petr Mladek
