(uvm_atopg) and use it in uvm_km_doputpage to replace some handrolled
code. Shrinks the kernel a trivial amount.

HPPA longjmp tests that the env parameter < the current stack pointer.
The test relies on the stack being at the end of the memory space.
This test is wrong for a couple of reasons:
- the main stack is at 0x78000000-0x80000000, but allocations between
0x80000000-0xc0000000 are available to the program,
- pthread stacks may be at any place in the address space, allowing a
heap-allocated env parameter to fail the check.

At various times diffs have had debugging that checked that we don't
insert a page into the tree on top of an existing page, leaking that
page's references. Until the recent hackathon (and introduction if
uvm_pagealloc_multi) the bufcache for example did a rb tree look up on
insert to check (under #ifdef DEBUG || 1) so instead just check it on
pageinsert every time, since RB_INSERT returns any duplicates so this
check is pretty much free.

argument to wdcreset(), to have it skip waiting until active channels see
their BUSY bit clear in the status register.
Use this feature in the resume path, during the first reset operation. The
first reset is supposed to only wake up the controller, and the disks don't
come back until the second reset is issued, therefore waiting for them to
report themselves as ready after the first reset, but before the second, is
moot - and as a matter of fact some controllers, such as the AMD 754 and
clones/offspring (e.g. Geode) keep the BUSY bit asserted after the first
reset.
Last, but not least, make sure wd@ata invokes wd_get_params() again before
returning from the resume code, as we will still be using polled transfers
for a short while.
This causes the Lemote Yeelong to resume within less than one second, instead
of the lousy 30 seconds wait between the two resets; and the wd_get_params()
voodoo prevents it from getting spurious ide interrupts afterwards.
wd_get_params() magic from dlg; rest of the work by yours truly after enough
prodding by dlg@ and pirofti@, among others. ok deraadt@ dlg@

(interrupt was not for me), 1 (positive interrupt was for me), or -1
(i am not sure...). We have continued with this practice in as many
drivers as possible, throughout the tree.
This makes some of the architectures use that information in their
interrupt handler calling code -- if 1 is returned (and we know
this specific machine does not have edge-shared interrupts), we
finish servicing other possible handlers on the same pin. If the
interrupt pin remains asserted (from a different device), we will
end up back in the interrupt servicing code of course... but this is
cheaper than calling all the chained interrupts on a pin.
This does of course count on shared level interrupts being properly
sorted by IPL.
There have been some concerns about starvation of drivers which
incorrectly return 1. Those drivers should be hunted down so that
they return -1.

acpi needs to use the apm definitions so that apmd speaks the same
language as it, so it uses the ones in apmvar.h these days.

smtpd now has an evpid associated to each delivery message, the evpid is an
u_int64_t where the upper 32 bits are the msgid, and the 32 bits are the
envelope unique identifier for that message. this results in lots of space
saved in both disk-based and ram-based queues, but also simplifies a lot of
code.
change has been stressed on my desktop, and has ran on my MX for the entire
afternoon without a regression.

are past. Use CLR() and SET() to modify necessary flags while leaving
the flags used by the buffer cache in peace.
Should make bufcache code much less confused about the state of the
bufs used in reading/writing disklabels. Other such flag abuses no
doubt await a visit.

be shared (p_sigignore, p_sigcatch, P_NOCLDSTOP, P_NOCLDWAIT) moves
to struct sigacts, wihle stuff that should be per rthread (ps_oldmask,
SAS_OLDMASK, ps_sigstk) moves to struct proc. Treat the coredumping
state bits (ps_sig, ps_code, ps_type, ps_sigval) as per-rthread
until our locking around coredumping is better.
Oh, and remove the old SunOS-compat ps_usertramp member.

using the -MD option to cc, with -MP, -MT, and -MF where needed, converting
"make depend" to a no-op. This increases parallelism for those using "make -j"
and keeps the dependencies up to date with each compilation automatically.

fsqueue_envelope_create(), fsqueue_message_purge()
- kill deprecated functions in queue_shared.c
At this point fsqueue backend is almost complete, all that is left to do is
to move the qwalk() API inside the queue_backend API, then make sure smtpd
is no longer calling anything queue related directly.

|
|
- change a few prototypes to allow bounce messages to use the
queue_backend API until it gets merged in
- kill functions of the queue API that have been deprecated

Arrandale (on laptop i3 and i5) was already doing this, but Clarkdale (the
desktop chipsets) wasn't. This gives mikeb@'s desktop a chance to get the video
back on resume.
While here, remove the vendor/subvendor ids from the Arrandale entry.
Just because someone doesn't have the same laptops as tested doesn't
mean inteldrm magically has the ability to restore the graphics chip.
This is possible to do without repost but fiddly and will take me a
while to sort out, so just repost the whole sodding lot for now.

- fsqueue->setup() performs the queue initialization;
- fsqueue->message() controls messages;
- fsqueue->envelope() controls envelopes;
This commit brings the following to fsbackend:
fsqueue_setup(), fsqueue_message_delete(), fsqueue_envelope_load(),
fsqueue_envelope_update(), fsqueue_envelope_delete().
It also makes smtpd use the queue_backend API for these operations.
