believe that there are PC98 systems with an OPTi chip.
I don't know enough about this special PC architecture to be sure about
this, so let's find out by letting people with such a system complain in
case this commit breaks the sound system for them. It's easy to revert
then.

same as today: do no power management. 1 means be conservative about
what you power down (any device class that has caused problems gets
added here). 2 means be agressive about what gets powered down (any
device class that's fundamental to the system is here). 3 means power
them all down, reguardless. The default is 1.
The effect in the default system is to add mass storage devices to the
list that we don't power down. From all the pciconf -l lists that
I've seen for the aac and amr issue, the bad device has been a mass
storage device class.
This is an attempt at a compromise between the very small number of
systems that have extreme issues with powerdown, and the very large
number of systems that gain real benefits from powerdown (I get about
20% more battery life when I attach a minimal set of drivers on my
Sony). Hopefully it will strike the proper balance.

* New definition CHN_F_HAS_VCHAN.
- channel.c
* Use CHN_F_HAS_VCHAN to mark channel with vchan capability instead
of relying on SLIST_EMPTY(&channel->children) == true for better
clarification and future possible usages of children (like
'slave' channel).
* Various fixes, including blocksize / format bps allignment,
better 24bit seeking (mplayer, others).
* Improve format chain building, it's now possible to record something
to a format non-native to the soundcard through various feeder format
converters or to higher sampling rate. This also gains another feature,
like doing vchan mixing on non s16le soundcard such as sb8.
- sound.c
* Increase robustness within various function that handle vchan
creation / termination (these function need a total rewrite, but
that would cause other major rewrite within various places too!).
As far as its robustness can be guaranteed, leave it as is.
* Optimize channel ordering, prefer *real* hardware playback
channels over virtual channels. cat /dev/sndstat should look
better.
* Increase sndstat verbosity to include bufsoft/bufhard allocation.
- vchan.c
* Fix LOR 119.
- http://sources.zabbadoz.net/freebsd/lor.html#119
* Reorder / increase robustness of vchan_create() / destroy().
Enforce destroy_dev() during destroy operation, fix possible
panic / dangling character device.
- http://lists.freebsd.org/pipermail/freebsd-current/2005-May/050308.html
* Tolerate a little bit more during mixing process, this should help
non s16le soundcards.
Note: Recoring in a non-native rate/format may result in overruns. A friendly
application is wavrec from audio/wavplay. The problem is under
investigation.

The vibra16X supports full duplex. I traced the Windows driver, and what is
does is that it programs one DMA channel 8-bit, and the other 16-bit. There
might be some kind of auto detection logic here, because it always uses 8-bit
for playback, even if I play 16-bit sound ...

locks were not aquired because the user buffers were not wired, thus it was
possible that that SYSCTL_OUT could sleep, causing a number of different
problems such as lock ordering issues and dead locks.
-Wire user supplied buffer to ensure SYSCTL_OUT will not sleep.
-Pickup ifnet locks to protect the list.
-Where applicable pickup address locks.
-Pickup radix node head locks.
-Remove splnet stubs
-Remove various comments about locking here, because they are no
longer needed.
It is the hope that these changes will make sysctl_rtsock MP safe.

Reduce the size of ed a little by removing some CIS based entries (others
likely can be removed too):
o The D-Link DFE-670TXD doesn't need its own entry based on strings.
o The Xircom CompactCard appears to be a TDK design, so list it there by ID
and remove the strings.
Increase the size of ed a little:
o Add support for the Addtron AE-660CT and Addtron AE-660. This is a very
generic NE-2000 clone (so generic that its CIS tags say NE-2000 generic
card!).
take the lock from interrupt context, which causes an implicit
lock order reversal. We've been using the lock carefully enough
that making it a spin lock should not be harmful.
first interface is detached from parent and then bpfdetach() is called.
If the interface was the last carp(4) interface attached to parent, then
the mutex on parent is destroyed. When bpfdetach() calls if_setflags()
we panic on destroyed mutex.
To prevent the above scenario, clear pointer to parent, when we detach
ourselves from parent.
UMA boot pages.
Disable recursion on the general UMA lock now that startup_alloc() no
longer uses it.
Eliminate the variable uma_boot_free. It serves no purpose.
Note: This change eliminates a lock-order reversal between a system

times consequently, without checking whether callout has been serviced
or not. (ng_pptpgre and ng_ppp were catched in this behavior).
- In ng_callout() save old item before calling callout_reset(). If the
latter has returned 1, then free this item.
- In ng_uncallout() clear c->c_arg.
Problem reported by: Alexandre Kardanev
First, mutexed callouts are incompatible with netgraph nodes, because
netgraph(4) can guarantee that the function will be called with mutex
held.
Second, nodes should not send data to their neighbor holding their
mutex. A node does not know what stack can it enter sending data in
some direction. May be executing will encounter a place to sleep.
New locking:
- ng_pptpgre_recv() and ng_pptpgre_xmit() must be entered with mutex held.
- ng_pptpgre_recv() and ng_pptpgre_xmit() unlock mutex before
sending data and then return unlocked.
- callout routines acquire mutex themselves.
