Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/livepatching
Pull livepatching updates from Jiri Kosina:
- RO/NX attribute fixes for patch module relocations from Josh
Poimboeuf. As part of this effort, module.c has been cleaned up as
well and livepatching is piggy-backing on this cleanup. Rusty is OK
with this whole lot going through livepatching tree.
- symbol disambiguation support from Chris J Arges. That series is
also
Reviewed-by: Miroslav Benes <mbenes@suse.cz>
but this came in only after I've alredy pushed out. Didn't want to
rebase because of that, hence I am mentioning it here.
- symbol lookup fix from Miroslav Benes
