Dmitry and I tried to figure out how soon does it need to run.
Nobody had a strong argument why it must run synchronously in the
hotplug path. Sure we want it as soon as possible and I'd say workqueue
is soon enough.
Existing hotplug path does not guaranty any ordering and original
microcode interface was driven from user-space. So clearly it was not
considered very critical.
