Define PTE used in the pmap module int terms of the bit definitions
in mmu_{51,40}.h.

Make compat_13_sigreturn13.s and compat_16_sigreturn14.s build as their
own stand-alone files and G/C the now-empty sigreturn.s.

Make sigcode.s and sunos_sigcode.s build as their own stand-alone files.

Make compat_13_sigreturn13.s and compat_16_sigreturn14.s build as their
own stand-alone files and G/C the now-empty sigreturn.s.

Build m68k/support.s on its own; don't include it from locore.s

G/C __HAVE_LEGACY_INTRCNT from the sun68k platforms.

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

G/C unreferenced copies of _spl() and _splraise().

We only need one copy of getvbr() and setvbr().

Make getsr() an inline in <m68k/psl.h> and G/C all of the now-redudant
copies.

Remove getsp(); nothing uses it.

s/paniced/panicked/ and s/borken/broken/ in comments.

Adjust the number of entries in the intrcnt array to match the number

Mostly merge changes from HEAD upto 20200411

 Fix typo in comment. Found by Wataru Ashihara.

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.

Rebase to HEAD as of a few days ago.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

avoid local redefinitions

sync with head

Move spread getsfc() and getdfc() functions into common m68k/support.s.

Note:
- ENTRY_NOPROFILE() is okay since they are used only for debug printf
- they are declared to return int so no need to put a return value into %a0

s/cpu_fork/cpu_lwp_fork/ in comment

Rename L_ADDR to L_PCB and amend some comments accordingly.

Kill proc0paddr.  Use lwp0.l_addr instead.

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.

Pass a frame pointer to trap() rather than the 'entire frame' trick.  Gcc4
was optimizing away modifications to the frame contents (it's not nice to
trick gcc).  Pass the pointer as the first argument to reduce the number
of places that would be changed otherwise.  Fixes the getcwd regression
test on most m68k ports.

Update to HEAD.

Adapt sun68k ports to yamt-idlelwp.
Tested on TME (sun2 and sun3) and 3/80 (sun3x).

merge ktrace-lwp.

Fix the sync with head I botched.

Centralize identical copies of proc_trampoline code.

(lots more opportunites here for the bored hacker, such as rei and trap0...)

make compile

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

Merge the nathanw_sa branch.

Catch up to -current

merge the 12 copies of vm_machdep.c on the m68k platforms.
clean up some other stuff along the way, including:
 - use m68k/cacheops.*, remove duplicates from cpu.h.
 - centralize a few declarations in (all the copies of) cpu.h.
 - define M68K_VAC on platforms which have a VAC.
 - switch the sun platforms to the (now common) proc_trampoline().
 - do the phys_map thang on the sun platforms too, no reason not to.

LWPify

Sync kqueue branch with -current.

Catch up to -current.

cpu_fork() -> cpu_lwp_fork().  This logically forks an LWP, not a
complete process.  As noted by Gregory McGarry on tech-kern.

Picked up some old scheduler changes.  Now the sun2 locore
corresponds tightly to revision 1.81 of the sun3 locore.

Tweaked whitespace and, in comments only, added % to make this
file much easier to compare to its sun3 cousin.

MD Scheduler Activation bits for Sun2.

XXX: I can't even compile-test this since the Sun2 config files
XXX: are borked both on the nathanw_sa branch and in -current ...

Update the kqueue branch to HEAD.

file locore.s was added on branch nathanw_sa on 2001-11-18 19:45:50 +0000

Under __ELF__, getvbr must return its pointer value
in %a0, not %d0.  This fixes many problems with
getting the PROM to halt and reboot the machine.

Merge Aug 24 -current into the kqueue branch.

Now treat the bus error register as 16-bits wide, even
though it has nothing in the top half.  Reading it as
only 8 bits can sometimes give erroneous values.  Under
DEBUG, also stash the value read in the buserr_reg global,
since the value is only latched until read.

Don't set up the g0 and g4 handlers here, now prom_abort()
does this.  Include the common m68k 16-bit aligned copy routines.

add missing   #include "opt_kgdb.h"

Many changes to support ELF.  Highlights include:
Added % to all register names.  The boot loader now
loads us exactly where we're linked, so no PIC or
remapping funny business.  Removed more 68881 code
that is only needed with the real silicon, which
a 68010 will never have.

Turned all lea/jsr combinations back into jbsrs,
as they were originally.

file locore.s was added on branch thorpej_scsipi on 2001-04-21 17:54:56 +0000

Under DIAGNOSTIC, disabled a test that was using an
instruction not available on the 68010.  Also removed
more old sun3 cache-related code.

Added some support for the old-school 'g0' and 'g4' monitor
hooks, and removed some old Sun3 cache and interrupt-register
related code.

Added.
