Switch hp300 over to the common interrupt dispatch code.

XXX There are still some things to fix up here, but it's no worse
than it was before (the problems date back to when we flattened
the device interrupt levels into IPL_VM).

Re-factor the 680x0 Function Code definitions into their own
separate file (as was done on the sun2/sun3 ports ages ago)
and switch everyone to the common header.

No need to export FC_PURGE here.

Stop using magic numbers for the MMU root pointer attributes and the
Translation Control register, and also get rid of "#if PGSHIFT == ..."
where those magic numbers are used.

Instead, define new macros: MMU51_SRP_BITS, MMU51_CRP_BITS, MMU51_TCR_BITS,
and MMU40_TCR_BITS, in terms of the definitions in mmu_{40,51}.h. These
automagically adapt to 8K and 4K pages based on the machine-specific value
of PGSHIFT.

G/C

G/C LS{SLEEP,RUN,ONPROC}

LWP status manipulation was moved out of assembly long ago.

branches: 1.45.6;
Remove compat_svr4 and compat_svr4_32, as discussed on tech-kern@ recently,
but also as discussed several times in the past.

branches: 1.44.58; 1.44.60;
Retire struct user, remove sys/user.h inclusions. Note sys/user.h header
as obsolete. Remove USER_TO_UAREA/UAREA_TO_USER macros.

Various #include fixes and review by matt@.

With a quick test, HP9000/362 doesn't seem to have frodo utility chip,
so probe code to identify HP362 taken from OpenBSD has never worked.

Identify HP362 by probing device IDs of the on-board framebuffer instead.

:

Move counting of faults, traps, intrs, soft[intr]s, syscalls, and nswtch
from uvmexp to per-cpu cpu_data and move them to 64bits. Remove unneeded
includes of <uvm/uvm_extern.h> and/or <uvm/uvm.h>.

Replace a couple of magic numbers with proper macro.

Rename L_ADDR to L_PCB and amend some comments accordingly.

Remove advertising clause for UCB in various genassym.cf files,

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

Introduce a new process state distinct from SRUN called SONPROC
which indicates that the process is actually running on a
processor. Test against SONPROC as appropriate rather than
combinations of SRUN and curproc. Update all context switch code
to properly set SONPROC when the process becomes the current
process on the CPU.

Fix the problem that single-step tracing of a trap instruction
drops the system into kernel debugger.

branches: 1.17.2; 1.17.4; 1.17.6;
Oops, forgot to add MMUID_385.

Identify the 385 and 425e. Partially from OpenBSD.

Add COMPAT_SVR4 for m68k.

branches: 1.14.4;
Hopefully get the last of the "ifdef UVM" bogons in genassym.cf's.

Define SYS_compat_13_sigreturn13.

Make sure SYS_exit and SYS___sigreturn14 are defined. Garbage collect
SYS_sigreturn.

Add support for UVM.

Garbage-collect VM_PMAP.

Garbage-collect pm_stchanged.

Eliminate references to vmspace.vm_pmap

Garbage-collect LED-related stuff.

- Define new machineid and mmuid constants.
- Rearrange slightly.

Nuke MDP_HPUXTRACE.

Fix a typo (oops).

oops, don't need trap.h here anymore

Don't genassym the trap type values; just include <machine/trap.h>

Use the script version to facilitate cross compiling.

Remove compat_svr4 and compat_svr4_32, as discussed on tech-kern@ recently,
but also as discussed several times in the past.

branches: 1.44.58;
Retire struct user, remove sys/user.h inclusions. Note sys/user.h header
as obsolete. Remove USER_TO_UAREA/UAREA_TO_USER macros.

Various #include fixes and review by matt@.

With a quick test, HP9000/362 doesn't seem to have frodo utility chip,
so probe code to identify HP362 taken from OpenBSD has never worked.

Identify HP362 by probing device IDs of the on-board framebuffer instead.

Move counting of faults, traps, intrs, soft[intr]s, syscalls, and nswtch
from uvmexp to per-cpu cpu_data and move them to 64bits. Remove unneeded
includes of <uvm/uvm_extern.h> and/or <uvm/uvm.h>.

branches: 1.41.4;
Replace a couple of magic numbers with proper macro.

Rename L_ADDR to L_PCB and amend some comments accordingly.

Remove advertising clause for UCB in various genassym.cf files,
which were derived from genassym.c in 4.4BSD-Lite2 (or 386BSD).
Closes PR misc/39573. Approved by martin@.

Remove ref to uvm.page_idle_zero

Don't reference m68k/saframe.h. Zed's dead, baby, Zed's dead.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

m68k/copy.s directly includes <sys/errno.h>.

Remove p_nras from struct proc - use LIST_EMPTY(&p->p_raslist) instead.
Remove p_raslock and rename p_lwplock p_lock (one lock is enough).
Simplify window test when adding a ras and correct test on VM_MAXUSER_ADDRESS.
Avoid unpredictable branch in i386 locore.S
(pad fields left in struct proc to avoid kernel bump)

SA_SIGINFO support for m68k (port specific changes)
