   Log Message:
   On x86, change the bus_space_tag_t to a pointer to a struct
   bus_space_tag.  For now, bus_space_tag's only member is
   bst_type, the type of space, which is either X86_BUS_SPACE_IO
   or X86_BUS_SPACE_MEM.  In the future, new bus_space_tag members
   will refer to override-functions installed by a new function,
   bus_space_tag_create(9).
   
   Add pointers to constant struct bus_space_tag, x86_bus_space_io and
   x86_bus_space_mem.  Use them to replace most uses of X86_BUS_SPACE_IO
   and X86_BUS_SPACE_MEM.
   
   Add an x86-specific bus_space_is_equal(9) implementation that compares
   the two tags' bst_type.

this needs a kernel version bump i believe.  old drivers
should be allowed to load anymore...  at the very least,
the *drm driver modules will be broken.

annoying that an MD change requires the MI version to bump
but these sorts of changes aren't too common i guess.

thanks.
