Keyword substitution: kv
Default branch: MAIN

Switch next68k over to common interrupt dispatch and G/C __HAVE_LEGACY_INTRCNT.
Also included is G/C of the old ssir stuff that's no longer used.

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 the values for the 68040 TT registers in terms of the definitions in
<m68k/mmu_40.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 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.

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,
which were derived from genassym.c in 4.4BSD-Lite2 (or 386BSD).
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 rest of m68k ports to yamt-idlelwp. Compile tested only.

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.  Nuke saframe.h

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.

catch up with -current on kqueue branch

Catch up to -current.

protect opt_compat_svr4.h with 'if defined(_KERNEL_OPT)', so that
this is usable from e.g. LKM context

MD Scheduler Activation bits for Next68k.
Compile-tested only.

Sync with HEAD.

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.

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.

Pull up to last week's -current.

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

Sync w/ -current.

SVR4-related typo in previous.

Add COMPAT_SVR4 for m68k.

Applied patches from Matt Debergalis <deberg@mit.edu>.
These patches include:
  Added framebuffer mapping for color framebuffer to support color wscons
    which is coming soon.
  Renamed wskbdmap_mfii[ch] to wskbdmap_next[ch]
  Changed video to be white on black instead of black on white.
  Now handles and discards mouse interrupts.
  Video and keyboard is now working on mono machines.

Applied supplied patches from pr port-next68k/6709
add bus_space support for mono framebuffer

Sync'ed more files and routines with mvme port in prepartion for UVM.
Now use generic m68k cachops everywhere rather than defining them in locore.s

Define SYS_compat_13_sigreturn13.

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