It is possible that there are CPUs with bits for both is_inserting and

If a CPU has both is_inserting and fw_remove set, the firmware processes
the
hotplug in that invocation and the unplug happens whenever the OSPM
triggers
the firmware next.
If these corner cases will actually work (I'm somewhat doubtful), that
will be really great.
Heh, yeah. That's a big if. I'll see if I can hit it in my testing.
Thanks
