in pmap_enter_ptpage(), if we are allowed to fail then fail rather than
waiting for memory to be available.  when we are mapping an anon or uobj page
then we will be holding the lock for that page owner, and sleeping to wait
for memory with a page owner lock held is illegal because the pagedaemon
can wait for that lock, which will lead to deadlock.  fixes PR 56932.

UVM locking changes, proposed on tech-kern:

- Change the lock on uvm_object, vm_amap and vm_anon to be a RW lock.
- Break v_interlock and vmobjlock apart.  v_interlock remains a mutex.
- Do partial PV list locking in the x86 pmap.  Others to follow later.

Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int.  The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER!  Some subsystems have

	#define min(a, b)	((a) < (b) ? (a) : (b))
	#define max(a, b)	((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX.  Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate.  But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all.  (Who knows, maybe in some cases integer
truncation is actually intended!)

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.

Use pool(9) for struct pv_entry allocations rather than
uvm_km_alloc(9)/uvm_km_free(9) and ancient homegrown pv_page_info structures.

Calling uvm_km_free(9) during pmap_remove(9) could cause rw_lock error
in uvm_unmap1() as noted in PR port-m68k/45519.

NetBSD/x68k (both real X68030 and XM6i emulator) still gets weird panic
(corrupted kernel stack pointer?) on some heavy load:
---
panic: MMU fault

db> tr
cpu_Debugger(4012004,8,1cbb528,2a618e0,2a5b000) + 6

but it also occurs without this change so there might be some more bugs
in m68k pmap...

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.

Split physical device segment pages from "managed" to "managed
device".  Cache that information as a flag PG_DEVICE so that callers
don't need to walk physsegs everytime.

Remove PQ_FIXED, which means that page daemon doesn't need to know
device segment pages at all.  But still fault handlers need to know
them.

I think this is what I can do best now.

Minor tweak to the pv_table management in the Hibler-derived m68k pmaps:
The head of the list is now a pv_header, which contains the first pv_entry
as well as a 16-bit attributes field (replaces the pmap_attributes array
plus the pv_entry::pv_flags field) as a 16-bit count of caller-specified
cache-inhibited mappings.

Tested on hp300 (shared pmap_motorola.c), changes to atari and amiga copies
are purely mechanical.

virtual_end, and protection_codes[] to common <m68k/pmap_motorola.h>,

XXX: avail_start and avail_end should also be moved, but it causes

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.

Pull up following revision(s) (requested by mhitch in ticket #177):
	sys/arch/m68k/m68k/pmap_motorola.c: revision 1.21
Common m68k pmap has same problem with 68060 after 17 month old uvm changes.
Tested and verified on my Amiga (yes, I'm hoping to switch amiga to using
the common pmp_motorola.c).
Uvm changes over 17 months ago resulted in the 68040/060 segment table
page being entered with pmap_kenter(), which does not record the mapping
in the pv table.  Attempting to inhibit caching of that page as required
by the 68060 hardware no longer changes the PTE and caused varying degrees
of multiple faulting, sometimes resulting in an unusable system.  Apparently
very few people attempted to run a 68060 based system since that change.
Fix to to change the caching bits directly rather than using pmap_changebit().

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).
