This makes no sense.

mcount isn't even one of the symbols that the patch by Adam is touching.

There's something else screwed up here. Not to mention that others
don't have your issue.

Do you have some other hacks in this area? Are you testing actual
plain 4.9, or do you (for example) still carry Arnd's patch around
that turned out to not work (reverted by f27c2f69cc8e in my tree)?
