hscbs may be traded during error recovery due to the way
we manage the qinfifo. This has the effect of changing the
index to the sense buffer even though the request sense command
references the original buffer. SCBs don't play this swapping
game and so serve as a more consistent reference.
- add a dma hack similar to the NetBSD one
- change PDQ_OS_MEM{RD,WR} to use readl/writel rather than deref'ing
a 32 bit va.
Note that I did just enough to get this working on alpha. I probably
should have updated it to use busspace, but I was too lazy to navigate
the twisty minefield of ifdefs that make up this driver.

2) Finalise the command in the case of CBI transfers with CCI (command

3) Remove a redundant bzero of a buffer.
The pccard_function_init() call creates a bunch of inactive resources
that are persistant and configured on demand. When the child driver
"allocates" a resource it is connected up to one of these. When the
child releases the resource, we should not delete our copy, just
deactivate it again. Otherwise there is nothing to recreate it again
after several probe functions have run and done an alloc/release cycle.
INVARIANTS shows 0xdeadc0de without this.
More work is needed to do a sweep though the pccard_function_disable()
call to actually delete the resources for real. Right now, we leak
memory on eject (at best), so Dont Do That(TM) yet. This affects
16 bit pccards on a cardbus bridge only. This will be fixed soon, but
for now it gets the cards working.

This fixes the problem where a probe routine establishes and
disestablishes the interrupt and then we get a panic in the probe
routine.
However, we pass the pointer to the interrupt hanlder count to the
parent bus, which writes its own cookie there, so there may be some
problems with that which isn't apparent at the moment.

but gets the wrong ethernet address).
o Fix OLDCARD to use the new interface.
o Rename the offsetp argument to deltap to more closely reflect what it

o Remove duplicate $FreeBSD$ in pccbb.c
o Allow deltap to be NULL.

In this case, make sure the driver doesn't leak any memory by freeing all
necessary buffers; make sure to loop and free all the previously allocated
mbufs in this routine.

- pccbb no longer needs to remember whether a card is inserted.
- pccbb reissues insertion on load of cardbus/pccard modules.
- got rid of unnecessary delays in power functions.
- Cardbus children are no longer deleted if probe/attach fails.
- non-attached child devices are reprobed at driver_added.
* CARD interface to read CIS
- added card_cis_read/card_cis_free interface to read arbitrary CIS
data. This currently is only implemented in cardbus.
* pccard begins to work
- pccard can now use higher memory space (and uses it by default).
- set_memory_offset interface changed.
- fixed ccr access, which was broken at multiple locations.
- implement an interrupt handler - pccard can now share interrupts.
- resource alloc/release/activate/deactivate functions gutted: some
resources are allocated by the bridge before the child device is
probed or attached. Thus the resource "belongs" to the bridge, and
the pccard_*_resource functions need to fudge the owner/rid.
- changed some error conditions to panics to speed debugging.
* Mutex fix - Giant is entered at the beginning of thread

- Add per-mixer mute status and saved mute_level so that the mixer_hwmute()
function can now toggle the mute state when the mute button is pressed.
- Create a dynamic sysctl tree hw.snd.pcmX when a pcm device is registered.
- Move the hw.snd.hwvol_* sysctl's to hw.snd.pcmX.hwvol_* so that they
are now properly device-specific. Eventually when the mixers become
their own devices these sysctl's will move to live under a mixerX tree.
- Change the interface of the hwvol_mixer sysctl so that it reports the
name of the current mixer device instead of the number and is settable
with the name instead of the number.
- Add a new function mixer_hwinit() used to setup the dynamic sysctl's
needed for the hwvol support that can be called by drivers that support
hwvol.

'chancount' never got up to equaling 'maxchans'. As a result,
pcm_makelinks() was never called, and one always had to set the sysctl to
get the /dev/mixer and other symlinks generated in the DEVFS case. Instead,
change the test in pcm_addchan() to call pcm_makelinks() after the first
channel is initialized, since the aliases are linked to channel 0.
