Woohoo, goodbye to bad rubbish.

FWIW, I plugged these into 4.8-rt (motto: if it's gonna go boom
anywhere, it'll likely do so in rt), and am beating the living crap out
of hotplug in parallel with routine tree merges, builds, serving nfs
etc etc, and all seems just peachy.  (If anything bad happens, I'll
move to a generic tree before reporting 'course)
