That fix _appears_ to have fixed up the runtime lockups I was hitting on
64 core box as well.  I don't have nohz_full enabled atm, but the nmi
watchdog was reliably barking either way, and while box could remain up
for quite a while, it should have died by now.  I'll let it grind away
for the rest of the weekend.
