Poul-Henning Kamp 2e27173fb5 Add a D_NOGIANT flag which can be set in a struct cdevsw to indicate ...

SPECFS will DROP_GIANT() ... PICKUP_GIANT() around calls to the
driver in question.

Notice that the interrupt path is not affected by this!

This does _NOT_ work for drivers accessed through cdevsw->d_strategy()
ie drivers for disk(-like), some tapes, maybe others.
