dumpdev. this occurs when we try to set the dumpdev to a device
with no driver loaded. this fixes PR#34872.
in sys_swapctl, if bdevsw_lookup() fails, set dumpdev = NODEV
before calling cpu_dumpconf(). (this also fixes PR#34872.)
XXX: cpu_dumpconf() should probably be changed to take a dumpdev
XXX: and return an error in such cases, but that is a much more
XXX: intrusive change.
XXX2: this is only run-tested on sparc64 and compile tested on a
XXX2: couple of platforms.
sun68k/include/intr.h.
This also means now sun3 has GENERIC_SOFT_INTERRUPTS support,
so also adapt fd.c and zs.c to MI softintr(9) APIs.
(I'll also update related sources in yamt-splraiseipl branch later)
with bus_space(9) support.
Note clock device name in obio.sun3 is renamed to oclock to use the same
MI attribute (intersil7170) with sun3x.
Tested on 3/80 and TME emulating 3/120 (but not on 3/4xx VME monsters).
bus_space_handle_t since bus space handle without bus space tag looks weird
- replace old sun3 obio_find_mapping() with new common find_prom_map()
- add bus_space_vaddr(), from hp300
- make sun3 port use common sun68k files as much as possible
- add temporary options _SUN2_ in std.sun2 until sun3 can share all
sun68k files (autoconf.c and isr.c are not yet)
- move sun68kvme declaration temporary as well from files.sun68k to files.sun2
- rename and move sun68k_find_prom_map() function to MD sources since it
can't be shared with sun3
- add bus tag members to struct confargs and initilize them where appropriate
XXX1: MD bus_dma(9) backends are not implemented (yet).
XXX2: more code (obio etc.) should be shared among sun3, sun3x and sun2.
- Add COMPAT_15 to all the kernel that had COMPAT_14, for the sake of coherency
- Remove the only occurences of #ifdef COMPAT_15 in the tree: for the ARM
ports, COMPAT_15 was always used in conjunction with EXEC_AOUT. Only EXEC_AOUT
matters here.

Currently "machine" symlink points sys/arch/sun68k/include,
but this means some <machine/foo.h> files are taken from
sys/arch/sun68k/include but others (i.e. files not in sun68k/include)
are taken from ${DESTDIR}/usr/include/machine.
Instead, make "machine" symlink point sys/arch/${MACHINE}/include,
make "sun68k" symlink point sys/arch/sun68k/include (not sys/arch/sun68k),
add sys/arch to include path, and move some files where appropriate.
Previously sun3x pmap assumed that pmap_unwire(9) was the only interface
which should handle unwiring page, but nowadays apparently it isn't true.
Fixes a longstanding "panic: get_a_table: out of A tables"
(and also B, C tables) problem on my 3/80.
While here, make this compile with PMAP_DEBUG.
ones and those for specific machines of developers. PR 32304.
OK'ed by rpaulo.
N.B. stf is a cloning device, so it still must be enabled by
"ifconfig stf0 create".
