5750ee293d Add a missing part of jhb's previous commit. It looks like he had a
patch chunk rejected that he missed.  This would manifest as a lock
assertion panic at boot (Giant not locked in kern_fork.c).

169299398a Undo the merger of mlock()/vslock and munlock()/vsunlock() and the

        src/sys/vm/vm_mmap.c            1.179
because different resource limits are appropriate for transient and
"permanent" page wiring requests.

Retain the kern_mlock() and kern_munlock() API in the revived
vslock() and vsunlock() functions.

Combine the best parts of each of the original sets of implementations
with further code cleanup.  Make the mclock() and vslock()
implementations as similar as possible.

Retain the RLIMIT_MEMLOCK check in mlock().  Move the most strigent
test, which can return EAGAIN, last so that requests that have no
hope of ever being satisfied will not be retried unnecessarily.

Disable the test that can return EAGAIN in the vslock() implementation
because it will cause the sysctl code to wedge.

acpi_thermal will not use higher cooling levels.  Reverse the logic so that

16df17d062 Put "failed to set signal flags properly for ast()" check under
DIAGNOSTIC instead of INVARIANTS.  INVARIANTS is intended for tests
that don't substantially change code flow or behavior (passive), but
this test required locking both the proc lock and scheduler lock
in order to execute.  It also appears to be a very advisory diagnostic
as opposed to an invariant violation.

16fc3635f7 Make NULL a (void*)0 whereever possible, and fix the warnings(-Werror)
that this provokes. "Wherever possible" means "In the kernel OR NOT
C++" (implying C).

There are places where (void *) pointers are not valid, such as for
function pointers, but in the special case of (void *)0, agreement
settles on it being OK.

Most of the fixes were NULL where an integer zero was needed; many
of the fixes were NULL where ascii <nul> ('\0') was needed, and a
few were just "other".

3b383f0922 In the last revision, I introduced a physical contiguity check that is both
unnecessary and wrong.  While it is necessary to verify that the page is
still free after dropping and reacquiring the free page queue lock, the
physical contiguity of the page can not change, making this check
unnecessary.  This check was wrong in that it could cause an out-of-bounds
array access.

51d22ccf42 - Some older Atheros drivers want KeInitializeTimer(), so implement it,
along with KeInitializeTimerEx(), KeSetTimer(), KeSetTimerEx(),
  KeCancelTimer(), KeReadStateTimer() and KeInitializeDpc(). I don't
  know for certain that these will make the Atheros driver happy since
  I don't have the card/driver combo needed to test it, but these are
  fairly independent so they shouldn't break anything else.

- Debugger() is present even in kernels without options DDB, so no
  conditional compilation is necessary (pointed out by bde).

- Remove the extra km_acquirecnt member that I added to struct kmutant
  and embed it within an unused portion of the structure instead, so that
  we don't make the structure larger than it's defined to be in Windows.
  I don't know what crack I was smoking when I decided it was ok to do
  this, but it's worn off now.

a787e5ecf8 Add sanity checks to the ndis_packet and ndis_buffer pool handling
routines to guard against problems caused by (possibly) buggy drivers.

The RealTek 8180 wireless driver calls NdisFreeBuffer() to release
some of its buffers _after_ it's already called NdisFreeBufferPool()
to destroy the pool to which the buffers belong. In our implementation,
this error causes NdisFreeBuffer() to touch stale heap memory.

If you are running a release kernel, and hence have INVARIANTS et al
turned off, it turns out nothing happens. But if you're using a
development kernel config with INVARIANTS on, the malloc()/free()
sanity checks will scribble over the pool memory with 0xdeadc0de
once it's released so that any attempts to touch it will cause a
trap, and indeed this is what happens. It happens that I run 5.2-RELEASE
on my laptop, so when I tested the rtl8180.sys driver, it worked fine
for me, but people trying to run it with development systems checked
out or cvsupped from -current would get a page fault on driver load.

I can't find any reason why the NDISulator would cause the RealTek
driver to do the NdisFreeBufferPool() prematurely, and the same driver
obviously works with Windows -- or at least, it doesn't cause a crash:
the Microsoft documentation for NdisFreeBufferPool() says that failing
to return all buffers to the pool before calling  NdisFreeBufferPool()
causes a memory leak.

I've written to my contacts at RealTek asking them to check if this
is indeed a bug in their driver. In the meantime, these new sanity checks
will catch this problem and issue a warning rather than causing a trap.
The trick is to keep a count of outstanding buffers for each buffer pool,
and if the driver tries to call NdisFreeBufferPool() while there are still
buffers outstanding, we mark the pool for deletion and then defer
destroying it until after the last buffer has been reclaimed.

4daf20b2f1 Increase kernel VA from 256Mb to 512Mb by shifting the segment used
for user copyinout down to 12, and keeping segments 13/14 for
kernel VA.

It would be nice to have more available, but segments lower than
this are reserved for either memory or 1:1 mapped device i/o,
and seg 15 is OpenFirmware ROM. Also, the effort to keep OpenFirmware
available for callbacks limits the use of VA-mapped segments.
Fortunately UMA_MD_SMALL_ALLOC takes away a lot of VM pressure.

707559e402 Check for TDF_SINTR before calling sleepq_abort() as there is a narrow
race in between sleepq_add() and sleepq_catch_signals() in that setting
td_wchan and TDF_SINTR is not atomic to sched_lock but only to the sleepq
lock.  This band-aid will stop assertion failures, but there is perhaps a
larger problem with the sleepq_add/sleepq_catch_signals race that I am not
sure how to solve.  For the signals case the race is harmless because we
always call cursig() after setting TDF_SINTR.  However, KSE doesn't do
anything in sleepq_catch_signals() to check that this race was lost, so I
am unsure if this race is harmful for this specific abort.

ea753400f0 The previous commit fixed -current on alpha for machines with
serial console connections but not graphical consoles.  This fixes the
graphical console machines.  It leaves the initial promcons console
driver in place until a bit later in the boot sequence, delaying the
switch to the device drivers more appropriate for the machine's real
console setup.  Note we still need the delayed make_dev() for promcons,
it does not have a proper bus interface so unlike other console drivers
it will not be found later during normal device discovery.

44f3b09204 Switch the sleep/wakeup and condition variable implementations to use the
sleep queue interface:
- Sleep queues attempt to merge some of the benefits of both sleep queues
  and condition variables.  Having sleep qeueus in a hash table avoids
  having to allocate a queue head for each wait channel.  Thus, struct cv
  has shrunk down to just a single char * pointer now.  However, the
  hash table does not hold threads directly, but queue heads.  This means
  that once you have located a queue in the hash bucket, you no longer have
  to walk the rest of the hash chain looking for threads.  Instead, you have
  a list of all the threads sleeping on that wait channel.
- Outside of the sleepq code and the sleep/cv code the kernel no longer
  differentiates between cv's and sleep/wakeup.  For example, calls to
  abortsleep() and cv_abort() are replaced with a call to sleepq_abort().
  Thus, the TDF_CVWAITQ flag is removed.  Also, calls to unsleep() and
  cv_waitq_remove() have been replaced with calls to sleepq_remove().
- The sched_sleep() function no longer accepts a priority argument as
  sleep's no longer inherently bump the priority.  Instead, this is soley
  a propery of msleep() which explicitly calls sched_prio() before
  blocking.
- The TDF_ONSLEEPQ flag has been dropped as it was never used.  The
  associated TDF_SET_ONSLEEPQ and TDF_CLR_ON_SLEEPQ macros have also been
  dropped and replaced with a single explicit clearing of td_wchan.
  TD_SET_ONSLEEPQ() would really have only made sense if it had taken
  the wait channel and message as arguments anyway.  Now that that only
  happens in one place, a macro would be overkill.

e5bb601d87 Drop sched_lock around the wakeup of the parent process after setting

dd75b0a90d Add an implementation of a generic sleep queue abstraction that is used
to queue threads sleeping on a wait channel similar to how turnstiles are
used to queue threads waiting for a lock.  This subsystem will be used as
the backend for sleep/wakeup and condition variables initially.  Eventually
it will also be used to replace the ithread-specific iwait thread
inhibitor.

Sleep queues are also not locked by sched_lock, so this splits sched_lock
up a bit further increasing concurrency within the scheduler.  Sleep queues
also natively support timeouts on sleeps and interruptible sleeps allowing
for the reduction of a lot of duplicated code between the sleep/wakeup and
condition variable implementations.  For more details on the sleep queue
implementation, check the comments in sys/sleepqueue.h and
kern/subr_sleepqueue.c.

47934cef8f Split the mlock() kernel code into two parts, mlock(), which unpacks
the syscall arguments and does the suser() permission check, and
kern_mlock(), which does the resource limit checking and calls
vm_map_wire().  Split munlock() in a similar way.

Enable the RLIMIT_MEMLOCK checking code in kern_mlock().

Replace calls to vslock() and vsunlock() in the sysctl code with
calls to kern_mlock() and kern_munlock() so that the sysctl code
will obey the wired memory limits.

Nuke the vslock() and vsunlock() implementations, which are no
longer used.

Add a member to struct sysctl_req to track the amount of memory
that is wired to handle the request.

Modify sysctl_wire_old_buffer() to return an error if its call to
kern_mlock() fails.  Only wire the minimum of the length specified
in the sysctl request and the length specified in its argument list.
It is recommended that sysctl handlers that use sysctl_wire_old_buffer()
should specify reasonable estimates for the amount of data they
want to return so that only the minimum amount of memory is wired
no matter what length has been specified by the request.

Modify the callers of sysctl_wire_old_buffer() to look for the
error return.

Modify sysctl_old_user to obey the wired buffer length and clean up
its implementation.

240160d48b Correct some major SMP-harmful problems in the pipe implementation. First
of all, PIPE_EOF is not checked pervasively after everything that can drop
the pipe mutex and msleep(), so fix.  Additionally, though it might not
harm anything, pipelock() and pipeunlock() are not used consistently.
Third, the kqueue support functions do not use the pipe mutex correctly.
Last, but absolutely not least, is a race: if pipe_busy is not set on
the closing side of the pipe, the other side that is trying to write to
that will crash BECAUSE PIPE_EOF IS NOT SET!  Unconditionally set
PIPE_EOF, and get rid of all the lockups/crashes I have seen trying
