John Baldwin 1b40801722 - When acknowledging interrupts, write the value 0xff to the interrupt 
status register rather than 0.  Without this, a single hardware volume
  event triggers an interrupt storm.
- Implement hardware volume control for the Maestro chips.  This version
  only handles the case where both channels are adjusted at the same time.

John Baldwin d0d4e34743 Add a new API for soundcards that have hardware volume control: 
- The mixer_hwmute() function can be called when a soundcard receives a
  mute request.
- The mixer_hwstep() function can be used to adjust the volume of one or
  both channels.
- The 'hw.snd.hwvol_step' sysctl determines the amount that mixer_hwstep()
  adjusts the volume by on each call.
- The 'hw.snd.hwvol_mixer' sysctl specifies the mixer device to adjust the
  volume on for both functions.  The values used correspond to the
  SOUNDCARD_MIXER_* constants.

John Baldwin b3b7ccfe38 Create a new sysctl node 'hw.snd' and move 'hw.sndunit' to 
'hw.snd.unit'.

Warner Losh a5eccf28a8 Add device id for the OZ Micro 6832. I didn't try to init it like the 
Cirrus Logic parts that end in 6832, but maybe some machines will need
that in the future.

Nicolas Souchu adb50a3799 Cleanup and improve mode detection. Now, you should get what you actually 
want according to the modes set with the ppc(4) flags. Especially, it
should fix some problems with mode detection of parallel chipsets
configured to EPP but which have timing troubles with the drives. In such
a case, the driver should now fall back to slower modes (PS2, NIBBLE).

John Baldwin 3e6831f510 The previous commit wasn't entirely correct. At least one goto to the 
out: label in psignal() did not grab sched_lock before trying to release
it.  Also, the previous version had several cases where it grabbed
sched_lock before jumping to out: unneccessarily, so rework this a bit.
The runfast: and out: labels must be called with sched_lock released, and
the run: label must be called with it held.  Appropriate mtx_assert()'s
have been added that should catch any bugs that may still be in this
code.

Peter Wemm e6de111aca Newbusify the PCI PDQ (fddi) attachment. This isn't as clean as 
the EISA attachment and has not been tested (no hardware!), but at least
it stands a chance at working.  At least it compiles now.

Matt Jacob 23dc42d12f Oops, I'm such an idiot. For reasons I don't really agree with, 
all devices are by default known by their 'cooked' name, so
my change was wrong. I thought it was a hangover from old 'block
tape device' support which hasn't worked (if it ever did) since
v6/PWB.

So, the default tape name is now the same as Linux. Far out, man....

Matthew Dillon 08c0a67b2e Fix a lockup problem that occurs with 'cvs update'. specfs's fsync can

Matt Jacob 56c6d0d775 Change the modification of what could be a const string. Apparently the 
construct:

	char *foo;
	...
	foo = "XXX";
	...
	foo[1] = 'Y';

is wrong. IT blew up on NetBSD-sparc64 because that platform write-protects
constant strings.
