sys: Use membar_release/acquire around reference drop.

This just goes through my recent reference count membar audit and
changes membar_exit to membar_release and membar_enter to
membar_acquire -- this should make everything cheaper on most CPUs
without hurting correctness, because membar_acquire is generally
cheaper than membar_enter.

sys: Membar audit around reference count releases.

If two threads are using an object that is freed when the reference
count goes to zero, we need to ensure that all memory operations
related to the object happen before freeing the object.

Using an atomic_dec_uint_nv(&refcnt) == 0 ensures that only one
thread takes responsibility for freeing, but it's not enough to
ensure that the other thread's memory operations happen before the
freeing.

Consider:

	  Thread A			  Thread B
	obj->foo = 42;			obj->baz = 73;
	mumble(&obj->bar);		grumble(&obj->quux);
	/* membar_exit(); */		/* membar_exit(); */
	atomic_dec -- not last		atomic_dec -- last
					/* membar_enter(); */
					KASSERT(invariant(obj->foo,
					    obj->bar));
					free_stuff(obj);

The memory barriers ensure that

	obj->foo = 42;
	mumble(&obj->bar);

in thread A happens before

	KASSERT(invariant(obj->foo, obj->bar));
	free_stuff(obj);

in thread B.  Without them, this ordering is not guaranteed.

So in general it is necessary to do

	membar_exit();
	if (atomic_dec_uint_nv(&obj->refcnt) != 0)
		return;
	membar_enter();

to release a reference, for the `last one out hit the lights' style
of reference counting.  (This is in contrast to the style where one
thread blocks new references and then waits under a lock for existing
ones to drain with a condvar -- no membar needed thanks to mutex(9).)

I searched for atomic_dec to find all these.  Obviously we ought to
have a better abstraction for this because there's so much copypasta.
This is a stop-gap measure to fix actual bugs until we have that.  It
would be nice if an abstraction could gracefully handle the different
styles of reference counting in use -- some years ago I drafted an
API for this, but making it cover everything got a little out of hand
(particularly with struct vnode::v_usecount) and I ended up setting
it aside to work on psref/localcount instead for better scalability.

I got bored of adding #ifdef __HAVE_ATOMIC_AS_MEMBAR everywhere, so I
only put it on things that look performance-critical on 5sec review.
We should really adopt membar_enter_preatomic/membar_exit_postatomic
or something (except they are applicable only to atomic r/m/w, not to
atomic_load/store_*, making the naming annoying) and get rid of all
the ifdefs.

pmap_remove_all(): Return a boolean value to indicate the behaviour.  If
true, all mappings have been removed, the pmap is totally cleared out, and
UVM can then avoid doing the work to call pmap_remove() for each map entry.
If false, either nothing has been done, or some helpful arch-specific voodoo
has taken place.

Allow only one pending call to a pool's backing allocator at a time.
Candidate fix for problems with hanging after kva fragmentation related
to PR kern/45718.

Proposed on tech-kern:
https://mail-index.NetBSD.org/tech-kern/2017/10/23/msg022472.html
Tested by bouyer@ on i386.

This makes one small change to the semantics of pool_prime and
pool_setlowat: they may fail with EWOULDBLOCK instead of ENOMEM, if
there is a pending call to the backing allocator in another thread but
we are not actually out of memory.  That is unlikely because nearly
always these are used during initialization, when the pool is not in
use.

Define the new flag too for previous commit.

pool_grow can now fail even when sleeping is ok. Catch this case in pool_get
and retry.

Assert that pool_get failure happens only with PR_NOWAIT.
This would have caught the mistake I made last week leading to null
pointer dereferences all over the place, a mistake which I evidently
poorly scheduled alongside maxv's change to the panic message on x86
for null pointer dereferences.

Since pr_lock is now used to wait for two things now (PR_GROWING and
PR_WANTED) we need to loop for the condition we wanted.
make the KASSERTMSG/panic strings consistent as '%s: [%s], __func__, wchan'
Handle the ERESTART case from pool_grow()

don't pass 0 to the pool flags
Guess pool_cache_get(pc, 0) means PR_WAITOK here.
Earlier on in the same context we use kmem_alloc(sz, KM_SLEEP).

use PR_WAITOK everywhere.
use PR_NOWAIT.

Don't use 0 for PR_NOWAIT

use PR_NOWAIT instead of 0

panic ex nihilo -- PR_NOWAITing for zerot

Add assertions that either PR_WAITOK or PR_NOWAIT are set.
- fix an assert; we can reach there if we are nowait or limitfail.
- when priming the pool and failing with ERESTART, don't decrement the number
  of pages; this avoids the issue of returning an ERESTART when we get to 0,
  and is more correct.
- simplify the pool_grow code, and don't wakeup things if we ENOMEM.

In pmap_enter_ma(), only try to allocate pves if we might need them,
and even if that fails, only fail the operation if we later discover
that we really do need them.  This implements the requirement that
pmap_enter(PMAP_CANFAIL) must not fail when replacing an existing
mapping with the first mapping of a new page, which is an unintended
consequence of the changes from the rmind-uvmplock branch in 2011.

The problem arises when pmap_enter(PMAP_CANFAIL) is used to replace an existing
pmap mapping with a mapping of a different page (eg. to resolve a copy-on-write).
If that fails and leaves the old pmap entry in place, then UVM won't hold
the right locks when it eventually retries.  This entanglement of the UVM and
pmap locking was done in rmind-uvmplock in order to improve performance,
but it also means that the UVM state and pmap state need to be kept in sync
more than they did before.  It would be possible to handle this in the UVM code
instead of in the pmap code, but these pmap changes improve the handling of
low memory situations in general, and handling this in UVM would be clunky,
so this seemed like the better way to go.

This somewhat indirectly fixes PR 52706, as well as the failing assertion
about "uvm_page_locked_p(old_pg)".  (but only on x86, various other platforms
will need their own changes to handle this issue.)
In uvm_fault_upper_enter(), if pmap_enter(PMAP_CANFAIL) fails, assert that
the pmap did not leave around a now-stale pmap mapping for an old page.
If such a pmap mapping still existed after we unlocked the vm_map,
the UVM code would not know later that it would need to lock the
lower layer object while calling the pmap to remove or replace that
stale pmap mapping.  See PR 52706 for further details.
hopefully workaround the irregularly "fork fails in init" problem.
if a pool is growing, and the grower is PR_NOWAIT, mark this.
if another caller wants to grow the pool and is also PR_NOWAIT,
busy-wait for the original caller, which should either succeed
or hard-fail fairly quickly.

implement the busy-wait by unlocking and relocking this pools
mutex and returning ERESTART.  other methods (such as having
the caller do this) were significantly more code and this hack
is fairly localised.
ok chs@ riastradh@

Don't release the lock in the PR_NOWAIT allocation. Move flags setting
after the acquiring the mutex. (from Tobias Nygren)
apply the change from arch/x86/x86/pmap.c rev. 1.266 commitid vZRjvmxG7YTHLOfA:

In pmap_enter_ma(), only try to allocate pves if we might need them,
and even if that fails, only fail the operation if we later discover
that we really do need them.  If we are replacing an existing mapping,
reuse the pv structure where possible.

This implements the requirement that pmap_enter(PMAP_CANFAIL) must not fail
when replacing an existing mapping with the first mapping of a new page,
which is an unintended consequence of the changes from the rmind-uvmplock
branch in 2011.

sun4v: Ensure that the W (Write) bit is not present in the TTEs unless for the data mapping. This way the permanent mappings for the primary cpu done by ofwboot are the same as the permanent mappings for the secondary cpus done by the kernel.

Update the DEBUG section at the tail of pmap_clear_modify().

Nothing prevents page modification after the modify bit was
cleared but before the DEBUG section checks pmap_is_modified(),
so remove this check.

For the same reason "modified" and "changed" may differ, so only
check "modified" implies "changed" here.

Welcome to 5.99.53!  Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
  New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
  the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
  Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

- Unify /dev/mem et al in MI code and provide required locking (removes
  kernel-lock on some ports).  Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

- replace smp_dcache_flush_page_all() with smp_dcache_flush_page_cpuset(),
  that flushes only on the set of CPUs not, everyone.  add new
  dcache_flush_page_cpuset() to flush this page from the D$ only
  on the specified set of CPUs.

- add a cpuset to pmap_free_page() and use it when freeing PTE pages
  when a pmap is destroyed

- introduce pmap_free_page_noflush(), and use it when we allocated a
  page for PTEs but didn't use it and don't need to flush it

- don't bother with pmap_lock in pmap_extract(), the only potential
  issue is pseg_get() which is already safe

XXX: workaround we'd like to remove when pmap / uvm locking is cleaned up:

- rename pseg_get() and pseg_set() to pseg_get_real() and pseg_set_real().
- if USE_LOCKSAFE_PSEG_GETSET is defined, which it current is by default,
  define pseg_[gs]et() in terms of functions that take a new pseg_lock
  mutex at IPL_VM while calling into the real functions.

this seems to avoid the pseg_set() crashes we've seen:
  1 - spare needed, when pseg_get() just worked for this pmap
  2 - the 2rd ldxa via ASI_PHYS_CACHED in pseg_set() loads garbage
      into %o4, and causes the 3rd ldxa to fault

blast_dcache() SMP friendly:

- blast_dcache() becomes sp_blast_dcache(dcache_size, dcache_line_size)
- new smp_blast_dcache(sparc64_cpuset_t) that blasts the D$ on this cpuset
- sparc64_ipi_blast_dcache() to support the above
- in pmap_remove_all(), when freeing mmu contexts for this pmap, mark
  the set of cpus to blast the d$ on as well and convert the
  blast_dcache() call into smp_blast_dcache() on the cpus who ran this
  pmap, or, sp_blast_dcache(dcache_size, dcache_line_size)
- convert the remaining blast_dcache() in machdep.c to sp_blast_dcache()
- in pmap_destroy()/pmap_remove_all() take the pmap_lock() always since
  we assert it is held always.

with these changes, NFS builds on the U60 seem to be stable now, and
the USIII machines also can often complete a single build.sh run now,
diskful or diskless.

Remove uarea swap-out functionality:

- Addresses the issue described in PR/38828.
- Some simplification in threading and sleepq subsystems.
- Eliminates pmap_collect() and, as a side note, allows pmap optimisations.
- Eliminates XS_CTL_DATA_ONSTACK in scsipi code.
- Avoids few scans on LWP list and thus potentially long holds of proc_lock.
- Cuts ~1.5k lines of code.  Reduces amd64 kernel size by ~4k.
- Removes __SWAP_BROKEN cases.

Tested on x86, mips, acorn32 (thanks <mpumford>) and partly tested on
acorn26 (thanks to <bjh21>).

Discussed on <tech-kern>, reviewed by <ad>.

Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

Make pmap_kernel() a MI macro for struct pmap *kernel_pmap_ptr,
which is now the "API" provided by the pmap module.  pmap_kernel()
remains as the syntactic sugar.

Bonus cosmetics round: move all the pmap_t pointer typedefs into
uvm_pmap.h.

Thanks to Greg Oster for providing cpu muscle for doing test builds.

Pull up following revision(s) (requested by martin in ticket #983):
	sys/arch/sparc64/include/kcore.h: revision 1.5
	lib/libkvm/kvm_sparc64.c: revision 1.11
	sys/arch/sparc64/sparc64/pmap.c: revision 1.201
Extend the sparc64 cpu kcore segment so that it records all kernel mappings
done via locked 4 MB pages. The old format could only record physically
continous kernel text mappings.
For compatibility reasons, just extend the structure and fill in all the
old fields as well.
Use the new sparc64 kcore cpu segment extensions to properly map VA/PAs
on kernels with more then 4 MB text/rodata segment.

We can not mutex_init() before setting up the per-CPU mappings needed
by curcpu() - a LOCKDEBUG kernel will die otherwise.

Modified Files:

	src/sys/arch/sparc64/sparc64: pmap.c

Log Message:
Extend the sparc64 cpu kcore segment so that it records all kernel mappings
done via locked 4 MB pages. The old format could only record physically
continous kernel text mappings.
For compatibility reasons, just extend the structure and fill in all the
old fields as well.

Modified Files:

Log Message:
Use the new sparc64 kcore cpu segment extensions to properly map VA/PAs

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.

currently it gets a double fault during a window save operation

In the INTSTACK and KSTACK_VA special case treatment in pmap_exctract,

allocate 128KB (as opposed to 64KB) per-cpu, and place the interrupt
stack, cpu_info structure, panicstack, idle uarea and normal kernel
stack in here.  the idle uarea and kernel stack are in the 2nd 64KB
page.  the interrupt stack and cpu_info structure are as the same
place in the 1st 64KB page, and the panicstack grows down from the
top of this page.  update comments in param.h to suit (XXX: a lot
of these constants should move to a header file that will not pollute
the name space so much.)  map these pages identically between
cpu_initialise() and cpu_mp_startup(), and deal with the two 64KB
pages in pmap_extract().  keep an unmapped 64KB page between them.

don't initialise the unused "ci_eintstack" member of the cpu_info
structure

use constants to initialise many addresses in the cpu_info structure,
consolidating these assignments from cpu0 and cpu>0

SMP cleanup.  provide support for multiple CPUs in DDB.  (SMP itself
is still not working.)

cpu.h:
- add a pointer for DDB regs in SMP environment to struct cpu_info
- remove the #defines for mp_pause_cpus() and mp_resume_cpus()
cpuset.h:
- remove CPUSET_ALL() and rename CPUSET_ALL_BUT() to CPUSET_EXCEPT()
  from petrov.
db_machdep.h:
- rename the members of db_regs_t to be the same as sparc
- change "db_regs_t ddb_regs" to "db_regs_t *ddb_regp" and change
  all references to suit
- redo DDB_REGS to no longer be a pointer to a fixed data structure
  but to one allocated per-cpu when ddb is entered
- move a bunch of prototypes in here
intr.h:
- remove SPARC64_IPI_* macros, no longer used
db_interface.c:
- change "db_regs_t ddb_regs" to "db_regs_t *ddb_regp" and change
  all references to suit
- make "nil" a 64 bit entity
- change the ddb register access methods to work in multiprocessor
  environment, it is now very much like sparc does it
- in kdb_trap() avoid accessing ddb_regp when it is NULL
- update several messages to include the cpu number
- unpause other cpus much later when resuming from ddb
- rename db_lock() to db_lock_cmd(), as the sparc-like code has
  db_lock as a simple lock
- remove "mach cpus" command, and replace it with "mach cpu" (which
  does the same) and also implement "mach cpu N" to switch to
  another cpus saved trapframe
db_trace.c:
- update for the ddb_regs -> ddb_regp change
genassym.cf:
- add TF_KSTACK as offsetof(struct trapframe64, tf_kstack)
ipifuncs.c:
- overhaul extensively
- remove all normal interrupt handlers as IPI's, we now handle
  them all specially in locore.s:interrupt_vector
- add a simplelock around all ipi functions - it's not safe for
  multiple cpus to be sending IPI's to each other right now
- rename sparc64_ipi_pause() to sparc64_ipi_pause_thiscpu() and,
  if DDB is configured, enable it to save the passed-in trapframe
  to a db_regs_t for this cpu's saved DDB registers.
- remove the "ipimask" system (SPARC64_IPI_* macros) and instead
  pass functions directly
- in sparc64_send_ipi() always set the interrupt arguments to 0,
  the address and argument of the to be called function.  (the
  argument right now is the address of ipi_tlb_args variable, and
  part of the reason why only one CPU can send IPI's at a time.)
  don't wait forever for an IPI to complete.  some of this is
  from petrov.
- rename sparc64_ipi_{halt,pause,resume}_cpus() to
  mp_{halt,pause,resume}_cpus()
- new function mp_cpu_is_paused() used to avoid access missing
  saved DDB registers
- actually broadcast the flush in smp_tlb_flush_pte(),
  smp_tlb_flush_ctx() and smp_tlb_flush_all().  the other end may
  not do anything yet in the pte/ctx cases yet...
kgdb_machdep.c:
- rework for changed member names in db_regs_t.
locore.s:
- shave an instruction from syscall_setup() (set + ld -> sethi + ld)
- remove some old dead debug code
- add new sparc64_ipi_halt IPI entry point, it just calls the C
  vector to shutdown.
- add new sparc64_ipi_pause IPI entry point, which just traps into
  the debugger using the normal breakpoint trap.  these cpus usually
  lose the race in db_interface.c:db_suspend_others() and end up
  calling the C vector sparc64_ipi_pause_thiscpu().
- add #if 0'ed code to sparc64_ipi_flush_{pte,ctx}() IPI entry
  points to call the sp_ version of these functions.
- in rft_kernel (return from trap, kernel), check to see if the
  %tpc is at the sparc64_ipi_pause_trap_point and if so, call
  "done" not "retry"
- rework cpu_switch slightly:  save the passed-in lwp instead of
  using the one in curlwp
- in cpu_loadproc(), save the new lwp not the old lwp, to curlwp
- in cpu_initialize(), set %tl to zero as well.  from petrov.
- in cpu_exit(), fix a load register confusion.  from petrov.
- change some "set" in delay branch to "mov".
machdep.c:
- deal with function renames
pmap.c:
- remove a spurious space
trap.c:
- remove unused "trapstats" variable
- add cpu number to a couple of messages

Alter sparc64 bootstrap, catch up to ofwboot v1.9:

 - Accept bootinfo structure passed down from ofwboot v1.9
 - Drop kernel re-mapping code
 - Use permanent 4MB mappings provided by the loader instead
 - Change kernel entry address to point directly at the code instead of pointing
   at the trap table's first slot. This allows the bootloader to detect
   those kernels which are aware of the new boot scheme
 - Due to the changes in kernel mapping code, alter secondary CPU bootstrap
   code to use trampoline just like FreeBSD does (some FreeBSD code is used
   here as well)

Cleanup: the PG_SZ macro was buggy (pointed out by Tim Newsham).
It was only used by (the also buggy/not ready for prime time) PMAP_PAGE_SIZE,
which in turn only was used in one place.

Get rid of all this and hardcode the result at the single place of use.

make sure we free the context for the pmap in pmap_destroy().
this usually isn't necessary since we freed it earlier in pmap_remove_all(),
but since uvmspace_free() is now called in the context of the exiting
process, a new context might be allocated if uvm_unmap_detach() decides
to sleep (since cpu_switch() will allocate a new context when it switches
back to the exiting process).

add support for non-executable mappings (where the hardware allows this)
and make the stack and heap non-executable by default.  the changes
fall into two basic catagories:

 - pmap and trap-handler changes.  these are all MD:
   = alpha: we already track per-page execute permission with the (software)
	PG_EXEC bit, so just have the trap handler pay attention to it.
   = i386: use a new GDT segment for %cs for processes that have no
	executable mappings above a certain threshold (currently the
	bottom of the stack).  track per-page execute permission with
	the last unused PTE bit.
   = powerpc/ibm4xx: just use the hardware exec bit.
   = powerpc/oea: we already track per-page exec bits, but the hardware only
	implements non-exec mappings at the segment level.  so track the
	number of executable mappings in each segment and turn on the no-exec
	segment bit iff the count is 0.  adjust the trap handler to deal.
   = sparc (sun4m): fix our use of the hardware protection bits.
	fix the trap handler to recognize text faults.
   = sparc64: split the existing unified TSB into data and instruction TSBs,
	and only load TTEs into the appropriate TSB(s) for the permissions.
	fix the trap handler to check for execute permission.
   = not yet implemented: amd64, hppa, sh5

 - changes in all the emulations that put a signal trampoline on the stack.
   instead, we now put the trampoline into a uvm_aobj and map that into
   the process separately.

originally from openbsd, adapted for netbsd by me.

Simplify the way the bounds of the managed kernel virtual address
space is advertised to UVM by making virtual_avail and virtual_end
first-class exported variables by UVM.  Machine-dependent code is
responsible for initializing them before main() is called.  Anything
that steals KVA must adjust these variables accordingly.

This reduces the number of instances of this info from 3 to 1, and
simplifies the pmap(9) interface by removing the pmap_virtual_space()
function call, and removing two arguments from pmap_steal_memory().

This also eliminates some kludges such as having to burn kernel_map
entries on space used by the kernel and stolen KVA.

This also eliminates use of VM_{MIN,MAX}_KERNEL_ADDRESS from MI code,
this giving MD code greater flexibility over the bounds of the managed
kernel virtual address space if a given port's specific platforms can
vary in this regard (this is especially true of the evb* ports).

Band aid - the infamous dcache_flush_page change independently suggested
by Andrey Petrov and Jason Thorpje (AFAIK).

This is a hack that covers some symptoms while we have no idea where
the real problem is. Anyway, since this avoids random data corruption
we better be safe and have this in-tree until the problem is solved the
right way.

Make the pmap count resident/wired mappings on the fly instead of
walking the page tables whenever this information is needed.

Add an option PMAP_COUNT_DEBUG to assert the new counts and the
page table walk agree.

The old solution had very bad performance impact, for example
by the high CPU load when running top(1).

Thanks to Simon Burge for pointing at the cause of the problem and
to Valeriy E. Ushakov for optimizing my simple minded assembler code.

fix two bugs in my last pmap rework:
 - in tlb_flush_all(), don't skip TLB entries with the high bit on,
   I was confused about which MMU register it was using.  it's also fine
   to use the last hardware context.
 - in pmap_create(), don't allocate a hardware context for the new pmap.
   it's unnecessary, and when this would cause us to recycle all the contexts,
   it would result in the current process's context being set to 0
   (ie. the kernel's context).  the current process could then return to
   userspace without going through the context-switch code (and thus without
   having a hardware context reallocated).  this would lead to user mappings
   being entered in the kernel's context later, causing all sorts of trouble.
   add some assertions to catch this kind of thing.

many improvements:
 - use struct vm_page_md for attaching pv entries to struct vm_page
 - change pseg_set()'s return value to indicate whether the spare page
   was used as an L2 or L3 PTP.
 - use a pool for pv entries instead of malloc().
 - put PTPs on a list attached to the pmap so we can free them
   more efficiently (by just walking the list) in pmap_destroy().
 - use the new pmap_remove_all() interface to avoid flushing the cache and TLB
   for each pmap_remove() that's done as we are tearing down an address space.
 - in pmap_enter(), handle replacing an existing mapping more efficiently
   than just calling pmap_remove() on it.  also, skip flushing the
   TSB and TLB if there was no previous mapping, since there can't be
   anything we need to flush.  also, preload the TSB if we're pre-setting
   the mod/ref bits.
 - allocate hardware contexts like the MIPS pmap:
   allocate them all sequentially without reuse, then once we run out
   just invalidate all user TLB entries and flush the entire L1 dcache.
 - fix pmap_extract() for the case where the va is not page-aligned and
   nothing is mapped there.
 - fix calculation of TSB size.  it was comparing physmem (which is
   in units of pages) to constants that only make sense if they are
   in units of bytes.
 - avoid sleeping in pmap_enter(), instead let the caller do it.
 - use pmap_kenter_pa() instead of pmap_enter() where appropriate.
 - remove code to handle impossible cases in various functions.
 - tweak asm code to pipeline a little better.
 - remove many unnecessary spls and membars.
 - lots of code cleanup.
 - no doubt other stuff that I've forgotten.

the result of all this is that a fork+exit microbenchmark is 34% faster
and a fork+exec+exit microbenchmark is 28% faster.

"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).

Pool deals fairly well with physical memory shortage, but it doesn't
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map).  Try to deal with this:

* Group all information about the backend allocator for a pool in a
  separate structure.  The pool references this structure, rather than
  the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
  to become available, but will still fail if it cannot callocate KVA
  space for the pages.  If this happens, carefully drain all pools using
  the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
  some pages, and use that information to make draining easier and more
  efficient.
* Get rid of PR_URGENT.  There was only one use of it, and it could be
  dealt with by the caller.

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.

the call to uvm_km_valloc() in pmap_init() can end up triggering a call to
pmap_growkernel() on large memory machines.  at this point we've already
called uvm_page_init(), so we can no longer use uvm_page_physget().
but the flag we use to decide whether to use uvm_page_physget() vs.
uvm_pagealloc() is only set at the end of pmap_init(), so we use
uvm_page_physget() anyway.  switch to using uvm.page_init_done to decide
how to allocate pages, since that's the real indicator of when we have to
change methods.

Another general cleanup:

Remove the entire idea of fasttrap interrupts since V9 traps are really cheap,
the CPUs are really fast, and the completely different trap frames would make
these handlers really difficult to implement.

pmap_changeprot() was only used by the clock and one other place; deprecate it.

probeget() and probeset() now take 64-bit addresses even in 32-bit mode so we
can probe IO locations by physical addresses.

Some pmap cleanup.

Changes for modified pmap_enter() API:
* Map the message buffer with access_type = VM_PROT_READ|VM_PROT_WRITE `just
  because'.
* Map the file system buffers with access_type = VM_PROT_READ|VM_PROT_WRITE to
  avoid possible problems with pagemove().
* Do not use VM_PROT_EXEC with either of the above.
* Map pages for /dev/mem with access_type = prot.  Also, DO NOT use
  pmap_kenter() for this, as we DO NOT want to lose modification information.
* Map pages in dumpsys() with VM_PROT_READ.
* Map pages in m68k mappedcopyin()/mappedcopyout() and writeback() with
  access_type = prot.
* For now, bus_dma*(), pmap_map(), vmapbuf(), and similar functions still use
  access_type = 0.  This should probably be revisited.
