Merge branch 'from-rusty/modules-next' into for-4.5/core
As agreed with Rusty, we're taking a current module-next pile through livepatching.git, as it contains solely patches that are pre-requisity for module page protection cleanups in livepatching. Rusty will be restarting module-next from scratch. Signed-off-by: Jiri Kosina <jkosina@suse.cz>
