No objections to the patch itself, but this link didn't work for me.

Replacing the 'g' with 'r' fixed it:

  https://lkml.kernel.org/r/cfba2c823bb984690b73572aaae1db596b54a082.1472137475.git.jpoimboe@redhat.com

Or, even better, I think Jiri doesn't rebase his livepatching 'for-next'
branch, so maybe just use the commit id:

  2992ef29ae01 ("livepatch/module: make TAINT_LIVEPATCH module-specific")
