cd8b53ed2d Omnibus PCI commit:
o Save and restore bars for suspend/resume as well as for D3->D0
	  transitions.
	o preallocate resources that the PCI devices use to avoid resource
	  conflicts
	o lazy allocation of resources not allocated by the BIOS.
	o set unattached drivers to state D3.  Set power state to D0
	  before probe/attach.  Right now there's two special cases
	  for this (display and memory devices) that need work in other
	  areas of the tree.

Please report any bugs to me.

aa95c5b148 Replace more ad-hoc versions of acpi_GetReference(). Since the type of
Reference objects changed from ACPI_TYPE_ANY to ACPI_TYPE_LOCAL_REFERENCE
in Oct. 2002, this may help systems where switching the cooler on failed.

2c1bb20746 Introduce a callout_drain() function. This acts in the same manner as
callout_stop(), except that if the callout being stopped is currently
in progress, it blocks attempts to reset the callout and waits until the
callout is completed before it returns.

This makes it possible to clean up callout-using code safely, e.g.,
without potentially freeing memory which is still being used by a callout.

9000d57d57 Associate a simple count of waiters with each condition variable. The
count is protected by the mutex that protects the condition, so the count
does not require any extra locking or atomic operations.  It serves as an
optimization to avoid calling into the sleepqueue code at all if there are
no waiters.

Note that the count can get temporarily out of sync when threads sleeping
on a condition variable time out or are aborted.  However, it doesn't hurt
to call the sleepqueue code for either a signal or a broadcast when there
are no waiters, and the count is never out of sync in the opposite
direction unless we have more than INT_MAX sleeping threads.

535eb30962 Add a new kernel option MUTEX_WAKE_ALL that changes the mutex unlock code
to awaken all waiters when a contested mutex is released instead of just
the highest priority waiter.  If the various threads are awakened in
sequence then each thread may acquire and release the lock in question
without contention resulting in fewer expensive unlock and lock
operations.  This old behavior of waking just the highest priority is
still used if this option is specified.  Making the algorithm conditional
on a kernel option will allows us to benchmark both cases later and
determine which one should be used by default.

e0098a5113 - Improved the TX performance with polling(4) by only checking the
status registers for error conditions and updating statistics
  when there are cycles left (inspired by the nge(4) driver).

- Removed the TX list counter and the producer/consumer gap; it's
  enough to just ensure we don't reuse the last (free) descriptor,
  as the chip may not have read its next pointer yet.  If we reuse
  it, the TX may stall under a heavy TX load with polling enabled.

- Dropped code to recharge the watchdog timer, it's pointless; the
  watchdog routine will re-init the chip and both RX and TX lists.

6a50285516 - The MiniportReset() function can return NDIS_STATUS_PENDING, in which
case we should wait for the resetdone handler to be called before
  returning.

- When providing resources via ndis_query_resources(), uses the
  computed rsclen when using bcopy() to copy out the resource data
  rather than the caller-supplied buffer length.

- Avoid using ndis_reset_nic() in if_ndis.c unless we really need
  to reset the NIC because of a problem.

- Allow interrupts to be fielded during ndis_attach(), at least
  as far as allowing ndis_isr() and ndis_intrhand() to run.

- Use ndis_80211_rates_ex when probing for supported rates. Technically,
  this isn't supposed to work since, although Microsoft added the extended
  rate structure with the NDIS 5.1 update, the spec still says that
  the OID_802_11_SUPPORTED_RATES OID uses ndis_80211_rates. In spite of
  this, it appears some drivers use it anyway.

- When adding in our guessed rates, check to see if they already exist
  so that we avoid any duplicates.

- Add a printf() to ndis_open_file() that alerts the user when a
  driver attempts to open a file under /compat/ndis.

With these changes, I can get the driver for the SMC 2802W 54g PCI
card to load and run. This board uses a Prism54G chip. Note that in
order for this driver to work, you must place the supplied smc2802w.arm
firmware image under /compat/ndis. (The firmware is not resident on
the device.)

Note that this should also allow the 3Com 3CRWE154G72 card to work
as well; as far as I can tell, these cards also use a Prism54G chip.

42d122e125 Converted the isa probe and attach to new-bus so that this driver works
without the (defunct) isa compatibility shims.  The new-bus-specific
parts are very similar to the ones for the pci probe and attach.

This was held up too long waiting for a repo copy to src/sys/dev/cy,
so I decided to fix the files in their old place.  This gives easier
to read and merge diffs anyway.

The "count" line in src/sys/conf/files won't be changed until after
the repo copy, so old kernel configs that specify a count need not be
(and must not be) changed until then.  The count is just ignored in
the driver.  One unfinished detail is dynamic allocation of arrays
with <count> and (<count> * 32) entries, and iteration over the arrays.
This is now kludged with a fixed count of 10 (up to 10 cards with up
to 32 ports each).

cc81fed63c Ever since rev 1.27 of puc.c, the port number that was exposed by puc(4)
and used by uart(4) for the channel conflicted with the port offset for
the Z8530. The Z8530 has the channels reversed (i.e. channel B is at
offset 0 and channel A is at offset 4). Assign the port offsets in the
right order so that uart(4) will properly attach to the channels.

8c9b7b2c84 Create NT_PRSTATUS and NT_FPREGSET notes for each and every thread
in the process. This is required for proper debugging of corefiles
created by 1:1 or M:N threaded processes. Add an XXX comment where
we should actually call a function that dumps MD specific notes.
An example of a MD specific note is the NT_PRXFPREG note for SSE
registers.

Since BFD creates non-annotated pseudo-sections for the first PRSTATUS
and FPREGSET notes (non-annotated in the sense that the name of the
section does not contain the pid/tid), make sure those sections describe
the initial thread of the process (i.e. the thread which tid equals the
pid). This is not strictly necessary, but makes sure that tools that use
the non-annotated section names will not change behaviour due to this
change.

The practical upshot of this all is that one can see the threads in
the debugger when looking at a corefile. For 1:1 threading this means
that *all* threads are visible.

fdcac92868 Assign thread IDs to kernel threads. The purpose of the thread ID (tid)
is twofold:
1. When a 1:1 or M:N threaded process dumps core, we need to put the
   register state of each of its kernel threads in the core file.
   This can only be done by differentiating the pid field in the
   respective note. For this we need the tid.
2. When thread support is present for remote debugging the kernel
   with gdb(1), threads need to be identified by an integer due to
   limitations in the remote protocol. This requires having a tid.

To minimize the impact of having thread IDs, threads that are created
as part of a fork (i.e. the initial thread in a process) will inherit
the process ID (i.e. tid=pid). Subsequent threads will have IDs larger
than PID_MAX to avoid interference with the pid allocation algorithm.
The assignment of tids is handled by thread_new_tid().

The thread ID allocation algorithm has been written with 3 assumptions
in mind:
1. IDs need to be created as fast a possible,
2. Reuse of IDs may happen instantaneously,
3. Someone else will write a better algorithm.

b08f499b32 Fixed a few bugs in the rl(4) driver:
Under polling(4), we counted non-existent output packets and wasted
CPU cycles, corrected.  (PR kern/64975.)

The fix in revision 1.71 to correct resetting of the watchdog timer
was wrong.

In rl(4), the TX list does not have a gap between the consumer and
producer, so the "empty TX list" test was wrong, corrected.

Also, resetting the timer to five each time we know there is still
some TX work to do was a bad idea -- under polling(4), if the chip
goes out to lunch, this results in the watchdog routine to _never_
be called.  Instead, let the timer downgrade to zero and fire the
watchdog, then reset it to five when it is zero AND there is some
TX work left.  (Most other network drivers need this fix too.)

6ec31f009a Performance tuning.
Moved the RX ring resyncing code to ste_rxeoc(), and only run it
if we were asked to POLL_AND_CHECK_STATUS, under DEVICE_POLLING.
(This significantly reduces the CPU load.)

Improved the RX ring resyncing code by re-checking if the head
is still empty before doing resyncing.  This mostly affects the
DEVICE_POLLING mode, where we run this code periodically.  We
could start checking with an empty head (well, an empty ring
even), and after doing a few iterations, the chip might write
a few entries, including the head, and we would bogusly consider
this case as requiring resyncing.  On a test box, this reduced
the number of resyncs done by a factor of 10.

In ste_txeof(sc), only reset the watchdog timer to zero when
the TX list is completely empty.

Converted ste_tx_prev_idx to a pointer -- faster.

Removed some bitrot.

36c6538b7f Change handling of probe response frames. Previously we always dropped the
refcnt on the node but left it in the node table.  This allows the node table
to hold the results of scanned ap's but for ibss scans left nodes w/o any
driver-private state setup and/or a bad refcnt (when the nodes were timed
out they were prematurely discarded).  Now we treat nodes identified for ap
scanning as before but force nodes discovered when scanning for ibss neighbors
to have complete/proper state and hold the refcnt on the node.  Any other
nodes created because of these frames are discarded directly (need to optimize
this case to eliminate various work that's immediately discarded).
