Log message:
amd64: MCOUNT_EXIT: restore interrupts, don't unconditionally reenable them
This bug can cause all sorts of problems, but in particular it was
most easily reproduced as a double fault in the syscall return path on
this CPU model:
Intel(R) Core(TM) i7-8650U CPU @ 1.90GHz
Tons of help from guenther@ in narrowing down the root cause. Fix
tweaked by guenther@. Additional input from deraadt@ and kettenis@.
ok guenther@
