Support the hardware-assisted AST on news68k in the common interrupt
stubs.

G/C __HAVE_LEGACY_INTRCNT from news68k.

Switch news68k over to the common interrupt dispatch code.

Remove duplicated / slightly-tweaked loadustp() (load user segment table)
routines from all of the m68k ports using the shared pmap.  Instead, in
pmap_init(), set up a function pointer to the appropriate mmu_load_urp*()
function in mmu_subr.s.

Define values for the 68030 TT registers in terms of the definitions
in <m68k/mmu_30.h> rather than using magic numbers.

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.

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.

Sync with HEAD, resolve a few conflicts

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

sync with head

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@.

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>.

Rename L_ADDR to L_PCB and amend some comments accordingly.

Use lwp_getpcb() on m68k ports, clean from struct user usage.

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

Closes PR misc/39573.  Approved by martin@.

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.

Adapt news68k to yamt-idlelwp. Tested on NWS-1750.

merge ktrace-lwp.

Sync with HEAD.

Add definitions for ports CTRL_POWER and CTRL_LED.

Backout previous because:
- we should fix genassym.sh to generate proper unsigned values rather than
  remove use of such values in each source
- 0xe0dc0000 is port to control LED so INTIOBASE1700_OFF is not proper name
- these LED debug code didn't work on news1200 and it should be fixed anyway

Convert expression for (0xe0dc0000-INTIOBASE1700) directly within a cpp
macro as otherwise gas gets handed an X - -Y expression and w 2.15 it won't
treat that as a valid expression

news68k/locore.s directly includes <machine/trap.h> and
m68k/copy.s directly includes <sys/errno.h>,
so remove definitions for them from assym.h.

Fix the sync with head I botched.

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)

Use PAGE_SIZE rather than NBPG.

Merge the nathanw_sa branch.

Catch up to -current.

sync kqueue with -current; this includes merge of gehenna-devsw branch,
merge of i386 MP branch, and part of autoconf rototil work

Add RAS offsets.

Remove <sys/map.h>

Don't need SAF_UPCALL anymore.

No longer need to pull in lwp.h; proc.h pulls it in for us.

file genassym.cf was added on branch nathanw_sa on 2001-11-18 18:42:19 +0000

Don't include opt_compat_svr4.h on building LKM.

Pull up revision 1.6 (requested by tsutsui):
  Allow runtime enabling/disabling of DC_BE and IC_BE bits in %cacr
  and enable them on news1200/1400/1500 (Which have no L2 cache); yields
  a performance improvement. Also correct a typo in a comment.

Define proper macros for FP frame offsets rather than magic numbers.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

file genassym.cf was added on branch thorpej_scsipi on 2000-11-20 20:16:15 +0000

Make it possible to enable/disable DC_BE and IC_BE bits in %cacr at runtime
and enable them on news1200/1400/1500 (which have no L2cache).

Add uvm_pageidlezero support. From x68k.

remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>

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.

Add news1200 support.
Based on a patch from Koichi NISHIWAKI <k-nis@ba2.so-net.ne.jp>

Pull up to last week's -current.

Initial import of news68k port.
