- 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
as multi-processor kernels. The old way made it difficult for kernel
modules to be portable between uni-processor and multi-processor
kernels. It is no longer necessary to jump through hoops.
- always load %fs with the private segment on entry to the kernel
- change the type of the self referntial pointer from struct privatespace
to struct globaldata
- make the globaldata symbol have value 0 in all cases, so the symbols
in globals.s are always offsets, not aliases for fields in globaldata
- define the globaldata space used for uniprocessor kernels in C, rather
than assembler
- change the assmebly language accessors to use %fs, add a macro
PCPU_ADDR(member, reg), which loads the register reg with the address
of the per-cpu variable member
- Provide TUNABLE_INT() hooks for ktr_cpumask, ktr_mask, and ktr_verbose
so that they can be set from the loader by their respective sysctl names.
For example, to turn on KTR_INTR and KTR_PROC in ktr_mask, one could
stick 'debug.ktr.mask="0x1200"' in /boot/loader.conf.

This is needed when linking statically as SVR4 (ie, ELF) behavior is to only
link in a module if it satisfies an undefined strong reference from somewhere.
(this surprises a lot of people) Things are different when using shared libs,
the entire library and its modules and their symbols are available at run-time
(when the weak reference is seen to still be unsatisfied and is satisfied on
the spot), this is not the case with static libs.
Thus one can have a static binary with unresolved week references, and at
run-time dereference a NULL pointer.

aic7xxx_freebsd.h:
Stubs for endian conversion functions. These will get filled
out once we get an official kernel api for this kind of thing

manual swaps #ifdefed by platform.
aic7xxx_pci.c
Allow the second channel of motherboard aic7896 chips to be attached.
It turns out that the encoding of the subdevice id differs between
PCI cards and MB based controllers and our check to see, via
the subvendor id, if the second channel was "stuffed" always
turned out negative.
BDECFLAGS; ANSIfy; use EXEC instead of "exec " where appropriate; use

get rid of static 'cache' style stuff by moving and sanitizing the
original SHELL checking code to main(), this also makes it easier to
free() the string; rename file-scope system() to exec_shell(); use
snprintf() everywhere instead of sprintf(); actually remember to free()
other malloc()'d char pointers in main().
I left out the -s option in this revision along with getusershell()
checking because of objections made by Warner Losh <imp> and Garrett
Wollman <wollman>. I agreed with their assertions that such code was
unnecessary in a program like this.
I dare people to make this coredump now.

o Eliminate trailing white space (while I'm here, just in a couple of places)
o wrap mostly at 80 columns (printf literal strings being the notable
exception)
o use return (foo) consistantly
o use 0 vs NULL more consistantly
o use queue(3) xxx_FOREACH macros where appropriate (some places used it
before, others didn't).
o use BSD line continuation parameters
Pendants will likely notice minor style(9) violations, but for the
most part the file now looks much much closer to style(9) and is
mostly self-consistant.

- 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.

to the SYSCTL_ADD_FOO() macros is a constant that should be turned into
a string via the pre-processor. Instead, require it to be an explicit
string so that names can be generated on the fly.
- Make some of the char * arguments to sysctl_add_oid() const to quiet

'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.

the file verifier. The NFS client is supposed to do a SETATTR after a
successful O_EXCL open/create to clean up the attributes. FreeBSD's
client code was generating a SETATTR rpc but was not generating an access

broken access time that solaris chokes on (and it doesn't look very
nice when you ls -lua under FreeBSD either!). Fixed.
