Switch the sun68k platforms over to the common m68k interrupt dispatch code.

Switch the sun68k platforms over to the common m68k vector table.

Make sun3 use common sun68k/sun68k/isr.c, sun68k/include/cpu.h and
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)

First attempt at bus_space(9) support for sun3 with common sun68k/bus.c:
- 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.

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

add a pair of new bus_dma(9) functions:
int _bus_dmatag_subregion(bus_dma_tag_t tag,
bus_addr_t min_addr,
bus_addr_t max_addr,
bus_dma_tag_t *newtag,
int flags)
void _bus_dmatag_destroy(bus_dma_tag_t tag)

that allow a (normally broken/limited) device to restrict the bus address
range it can talk to. this is used by bce(4) to limit DMA addresses to
1GB range, the maximum the chip can address.

move some per-cpu data definitions to MI place so that they can be modified
without touching all ports. discussed on tech-kern@.

Rearrange process exit path to avoid need to free resources from different
process context ('reaper').

From within the exiting process context:
* deactivate pmap and free vmspace while we can still block
* introduce MD cpu_lwp_free() - this cleans all MD-specific context (such
as FPU state), and is the last potentially blocking operation;
all of cpu_wait(), and most of cpu_exit(), is now folded into cpu_lwp_free()
* process is now immediatelly marked as zombie and made available for pickup
by parent; the remaining last lwp continues the exit as fully detached
* MI (rather than MD) code bumps uvmexp.swtch, cpu_exit() is now same
for both 'process' and 'lwp' exit

uvm_lwp_exit() is modified to never block; the u-area memory is now
always just linked to the list of available u-areas. Introduce (blocking)
uvm_uarea_drain(), which is called to release the excessive u-area memory;
this is called by parent within wait4(), or by pagedaemon on memory shortage.
uvm_uarea_free() is now private function within uvm_glue.c.

MD process/lwp exit code now always calls lwp_exit2() immediatelly after
switching away from the exiting lwp.

http://mail-index.netbsd.org/tech-userlevel/2011/08/25/msg005404.html
This is used by disk tools such as disklabel(8) to dynamically decide is
the undelyling platform uses a disklabel-in-mbr-partition or not
(instead of using a compile-time list of ports).
getlabelusesmbr() reads the sysctl kern.labelusesmbr, takes its value from the
machdep #define LABELUSESMBR.
For evbmips, make LABELUSESMBR 1 if the platform uses pmon
as bootloader, and 0 (the previous value) otherwise.

Reverted previous commit. It was meant to fix a problem that
was already fixed by nathanw, had I bothered to check.

Now make a machine/ directory with symlinks to a small number
of machine-specific headers. When ${MACHINE} is sun2, this
allows building the sun3 and sun3x parts of libsa, which need
things like <machine/param3.h> and <machine/param3x.h> to be
#includeable.

Make sun68k/stand build without installed ${DESTDIR} files.

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.

Always set CFLAGS, CPUFLAGS, and COPTS explicitly like i386/stand
to override settings in /etc/mk.conf, so that build won't fail
in sun68k which contains both sun2 and sun3 sources.

They requires a special calling convention to udivsi3, and cannot to be

there's no problem for using them in a controlled situation, i.e., kernel
and standalone programs.

Note that this does not affect at all m68k ports other than sun2, since
codes generated by gcc do not call these routines.

Assembler files are moved from common/lib/libc/arch/m68k/gen to

branches: 1.31.8;
Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

- change find_prom_map() to take paddr_t and return vaddr_t rather than
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

First attempt at bus_space(9) support for sun3 with common sun68k/bus.c:
- 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.
