Update of /cvsroot/src/sys/arch/i386/i386
In directory netbsd1:/var/slash-tmp/cvs-serv8463

Modified Files:
        machdep.c 
Log Message:
figure out which space we're using in i386_memio_{map,alloc,unmap} by
doing 'if (tag == ...) else if (tag == ...) else panic' rather than
by doing a switch.  This makes life easier for people who need
the i386 bus_space_* functions to access spaces other than the normal
memory and I/O spaces, because it allows them to define an i386
bus_space_tag_t as a pointer to a function table, rather than just
an int.  (They could define it as an int and cast it to a funtion
table pointer, but I think that's bad karma, and this change doesn't
hurt.)
