JFYI, the patch has been committed into livepatching.git,
branch for-7.3/trivial.

The problem does not look serious enough to deserve rushing into
an 7.2-rcX. Also it is touching the global Makefile so it should
spent some time in linux-next. Let me know if you would prefer
to get it faster into the mainline.
