        src/sys/external/bsd/drm2/include/linux [riastradh-drm2]: io-mapping.h

Log Message:
Just use bus_space_map for io-mapping, and limit to one at a time.

Reserving the whole region interferes with other parts of the driver
which want to map it in different ways.  It also horrifically wastes
space when actually mapped, because there's no way to map a subregion
of a reservation.  And the bus_space_reservation API is x86-only at
the moment.
