Arrange to update cached LWP credentials in userret() rather than during
syscall/trap entry, eliminating a test+branch on every syscall/trap.

This wasn't possible in the 3.99.x timeframe when l->l_cred came about
because there wasn't a reliable/timely way to force an ONPROC LWP running on
a remote CPU into the kernel (which is just about the only new thing in
this scheme).

Overhaul the API used to fetch and store individual memory cells in
userspace.  The old fetch(9) and store(9) APIs (fubyte(), fuword(),
subyte(), suword(), etc.) are retired and replaced with new ufetch(9)
and ustore(9) APIs that can return proper error codes, etc. and are
implemented consistently across all platforms.  The interrupt-safe
variants are no longer supported (and several of the existing attempts
at fuswintr(), etc. were buggy and not actually interrupt-safe).

Also augmement the ucas(9) API, making it consistently available on
all plaforms, supporting uniprocessor and multiprocessor systems, even
those that do not have CAS or LL/SC primitives.

Welcome to NetBSD 8.99.37.

Refactor the 68040 writeback() from each m68k port's trap handler into a
shared copy: m68040_writeback().  It is essentially a copy of the Atari
version, with some minor cosmetic tweaks and one small performance optimization
from the mvme68k port.

Tested by rjs@ on a Quadra 950.  (Thanks!)

Change how we make SA threads not generate upcalls. Instead of clearing
LW_SA, use a private flag, LP_SA_NOBLOCK, that we set when we want
to not generate upcalls. This means we do NOT need to lock (l)
(ourselves) to set it.

Adjust tests that look at LW_SA. Now, we are an upcall-generating
lwp if ((l->l_flag & LW_SA) && (~l->l_pflag & LP_SA_NOBLOCK)).

Introduce code pattern to set & remember this:

	f = ~l->l_pflag & LP_SA_NOBLOCK;
	l->l_pflag |= LP_SA_NOBLOCK;

	...

	/* f is now LP_SA_NOBLOCK if it wasn't set in l_pflag before */

	l->l_pflag ^= f;

I updated a lot of the trap handlers to do trap handling iff LP_SA_NOBLOCK
is not set. I tried to figure out if the trap handler could be triggered
for user-based faults as opposed to kernel faults to user addresses, and
only look at LP_SA_NOBLOCK for the latter.

Above is a result of discussions with rmind at to reduce lock twiddling.

Also, per same discussions, add locking to sys_sa_preempt(). p_lock is
the lock we want.

Also, per same discussions, remove use of LSSUSPENDED as a thread state.
We needed to use it when we were emulating the 4.X and previous behavior
of hiding cached threads. For the moment, we now have them instead
remain visible to all and have them sleeping on the "lwpcache" wait
channel.

sa_newcachelwp(): sa_putcachelwp() wants savp_mutex held, not p_lock.

Tweak some comments.

Per discussion with ad at n dot o, revert signal mask handling
changes.

The l_sigstk changes are most likely totally un-needed as SA will
never use a signal stack - we send an upcall (or will as other
diffs are brought in).

The l_sigmask changes were too controvertial. In all honesty, I
think it's probably best to revert them. The main reason they were
there is the fact that in an SA process, we don't mask signals per
kernel thread, we mask them per user thread. In the kernel, we want
them all to get turned into upcalls. Thus the normal state of
l_sigmask in an SA process is for it to always be empty.

While we are in the process of delivering a signal, we want to
temporarily mask a signal (so we don't recursively exhaust our
upcall stacks). However signal delivery is rare (important, but
rare), and delivering back-to-back signals is even rarer. So rather
than cause every user of a signal mask to be prepared for this very
rare case, we will just add a second check later in the signal
delivery code. Said change is not in this diff.

This also un-compensates all of our compatability code for dealing
with SA. SA is a NetBSD-specific thing, so there's no need for
Irix, Linux, Solaris, SVR4 and so on to cope with it.

As previously, everything other than kern_sa.c compiles in i386
GENERIC as of this checkin. I will switch to ALL soon for compile
testing.

Initial checkin of re-adding SA. Everything except kern_sa.c
compiles in GENERIC for i386. This is still a work-in-progress, but
this checkin covers most of the mechanical work (changing signalling
to be able to accomidate SA's process-wide signalling and re-adding
includes of sys/sa.h and savar.h). Subsequent changes will be much
more interesting.

Also, kern_sa.c has received partial cleanup. There's still more
to do, though.

Merge proc::p_mutex and proc::p_smutex into a single adaptive mutex, since
we no longer need to guard against access from hardware interrupt handlers.

Additionally, if cloning a process with CLONE_SIGHAND, arrange to have the
child process share the parent's lock so that signal state may be kept in
sync. Partially addresses PR kern/37437.

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.

68030 and 68040 processors consider the read portion of a read-modify-write
transfer as a write to ensure the memory is writable before starting any
transfer.  The fault status information does not reflect this in the 'read'
status bit (i.e. it shows up as a read access), so faults with a RMW access
to non-writable memory was not getting the correct protection.  The page would
be read-only and the instruction would fault over and over.
A specific example is when a process forks, and the child process attempts
to execute a RMW access to a data page, which is read-only because it's CoP
Copy-On-Write.
When checking if the page needs to be writablek, also check the locked transfer
and treat any locked transfer as a write.
68060 already handled this correctly, since it has separate read and write
fault bits, and both are set on a RMW access and the trap code was checking
the write status bit.
Fixes PR#36848.

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.

* In kpsendsig(), use KSI_TRAP_P() to select the lwp that gets the signal.
  Inspired by Matthias Drochner's fix to kpsendsig(), but correctly handles
  the case of non-trap-generated signals that have a > 0 si_code.

This patch fixes a signal delivery problem with threaded programs noted by
Matthias Drochner on tech-kern.

As discussed on tech-kern.  Reviewed and OK's by Christos.

In the SA universe, the switch-to-this-LWP decision is made at a
different level than where preempt() calls are made, which renders
the "newlwp" argument useless.  Replace it with a "more work to do"
boolean argument.  Returning to userspace preempt() calls pass 0.
"Voluntary" preemptions in e.g. uiomove() pass 1.  This will be used
to indicate to the SA subsystem that the LWP is not yet finished in
the kernel.

Collapse the SA vs. non-SA cases of preempt() together, making the
conditional code block much smaller, and don't call sa_preempt() if
more work is to come.

NOTE: THIS IS NOT A COMPLETE FIX TO THE preempt()-in-uiomove() PROBLEM
THAT CURRENTLY EXISTS FOR SA PROCESSES.

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.

Curproc->curlwp renaming.

Change uses of "curproc->l_proc" back to "curproc", which is more like the
original use. Bare uses of "curproc" are now "curlwp".

"curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL)
so that it is always safe to reference curproc (*de*referencing curproc
is another story, but that's always been true).

Update pmap_update to now take the updated pmap as an argument.
This will allow improvements to the pmaps so that they can more easily defer expensive operations, eg tlb/cache flush, til the last possible moment.

Currently this is a no-op on most platforms, so they should see no difference.

Initial import of the known working kernel bits for the NetBSD/cesfic
port. cesfic is a VME board with one or two mc68040 processors. See
the README file for details.
The port is working well with a.out userland, there are some problems
with ELF still, like applications running out of memory where it is not
expected. Some parts, in particular the pmap (which was taken from hp300
four years ago), need updating, but this is easier done within the NetBSD
CVS tree.
