Without this, ioctl commands for setting formats and speeds were
essentially ignored for simplex devices until the application actually
performed a read or write.
* Make sure that both channels are set in the SB mixer code and provide a
mixer table specifically for the ess18xx which supports the extended
accuracy available on this part.
* Fix a stupid bug in ess_format() which ignored the passed-in format and
changed the hardware based on the value which was set last time. This
meant that the hardware setting was often not set correctly at all.
* Add a custom identify driver for the ESS1888 which automagically detects
and adds the device in a pseudo-PnP way. This driver also emits the magic
sequence which enables the sound hardware after a hard reset, allowing
it to work correctly for the sound hardware of a PWS 433au (and probably
all other PWS class alpha machines).
With these changes, I was able to play back simple sounds on my 433au. I
have not tested recording or any other formats other than 8bit ulaw and
16bit stereo.

Rename a few (I wish companies would stop buying each other)
Add a quirk entry for hubs that say they are self powered but are
in fact bus powered (usage in uhub follows shortly).
condition for Short transfers.
Change the scheduling to Depth first. We now transfer as many TD's as
possible from QH before moving to the next queue (Breadth first). It should
still be verified that this does not lead to starvation in a busy system
(in the case were transfers are added to the beginning of the control
or bulk queues).
during autoconfig to support strange hardware (such as the Yamaha DS-1)
which implements 'legacy' ISA devices as well as a PCI device. This will
allow the PCI driver for the YMF724 to add the legacy devices to the ISA
bus and will allow the PnP system to automatically allocate the resources
for those devices.
The old code was spread out through the machdep code and was sloppy about
enabling and disabling the FEN bit (which controls access to the FP
register set). This caused a DIAGNOSTIC warning "DANGER WILL ROBINSON:
FEN SET IN cpu_fork!" sometimes when operating under high loads and could
conceivably lead to processes getting incorrect FP results.
The new code is much more strict about the FEN bit and makes sure that
*only* fpcurproc ever has it enabled. This also allows us to remove a
section of code from the exception_return path which might improve
performance marginally.

instead of duplicating the code. (2) If a wired page is passed
to vm_page_free_toq, panic instead of printing a friendly warning.
(If we don't panic here, we'll just panic later in vm_page_unwire
obscuring the problem.)
Correctly lock vnodes when calling VOP_OPEN() from filesystem mount code.
Unify spec_open() for bdev and cdev cases.
Remove the disabled bdev specific read/write code.
It however posts a bogus button up event once in a while. Whenever
we receive dx=dy=dz=buttons=0 we postpone adding it to the queue for
50msecs with a timeout. If in the meantime something else is posted
the event is ignored.
This avoids the problem Nik Sayer reported. He noticed that X windows
would drop and pick up a window once in a while.
Thanks, Nik, for supplying me with the keyboard to fix the problem!
Try to use a 32bit mask on the IO addresses, this fixes the alpha
and hopefully doesn't break on any i386 machines.
Try to enable both read & write cache on disks, they should be as
default, but better be sure..
