Hi,
as I was using non-standard CC list, I didn't use my usual pull request
script, and as a result forgot to CC live-patching@ on this one.
Apologizes for that, resending at least this way so that it hits ML
archive.

Subject: [GIT PULL] livepatching for 4.7
Linus,
please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/jikos/livepatching.git for-linus
to receive the following livepatching updates for 4.7 merge window:
- removal 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
