was optimizing away modifications to the frame contents (it's not nice to
trick gcc). Pass the pointer as the first argument to reduce the number
of places that would be changed otherwise. Fixes the getcwd regression
test on most m68k ports.
or the m68k common pmap_motorola.c. Add comment-out entry for
m68k/m68k/pmap_motorola.c. Currently still uses amiga pmap, but switching
to m68k common pmap_motorola is done easily for testing.
pointers from pmap_bootstrap(), and make pmap_bootstrap() more compatible
with the common m68k pmap_motorola.c.

other m68k ports (initially from the yamt-km branch a long time ago).
- move Sysmap to the end of address space.
- move Amiga hardware mapping to immediately after Sysptmap.
- tweak virtual_avail/end accordingly.
A DEBUG kernel should now boot without panicing. Also, kernel address space
layout is now compatible with m68k/m68k/pmap_motorola.c.
is@. Even though the argument type changes as an effect of the
caddr_t removal, there really is no need to indirect where we didn't
before. Instead, add the appropriate cast.
an SR value or an IPL_* constant).
- Take advange of the smaller ipl_cookie_t to shrink kmutex_t from
16 bytes to 8 bytes by overlapping storage where possible.
- Implement a RAS-based _lock_cas() for mc68010 systems (Sun2). See
sun68k/sun68k/isr.c.
Tested on various m68k platforms, but NOT Sun2. In any case, at least
Sun2 compiles now.
Try to preserve `volatile' qualification where possible, though
uses of kvtop() gain an unfortunate but probably unavoidable __UNVOLATILE().
Correct various instances of "void *ba, fb" to have * in front of fb as well.
