32k read and write operations on datagram sockets when in fact we
reject requests larger than 16k. It must be the case that virtually
all clients use data sizes of 16k or less for UDP transport (FreeBSD's
client defaults to 8k and never exceeds 16k), as this bug has been
present ever since NFSv3 support was added.

The correct range is [1...7] with Sunday=1, but we have been writing
[0...6] with Sunday=0.
The Soekris computers flagged the zero, zapped the date, so if you
rebooted your soekris on a sunday, it would come up with a wrong
date.
Bruce has a more extensive rework of this code, but we will stick with
the minimalist fix for now.

This mostly consists of functionality to serialize accesses to
the two ATA channels (which can also be used to "fix" certain
PCI based controllers).
Add support for Acard controllers.
Enable the ATA driver in PC98 GENERIC, and add device hints.
Update man page with latest support.
The PC98 core team has kindly provided me with a PC98
machine that made this all possible, thanks to all that
contributed to that effort, without that this would
probably newer have been possible..

zeroed results to be written instead of the proper contents.
Conversely, when the block is going to be entirely filled in, it
is not necessary reread the old contents.

We allow the request to go through if it matches either a prefetchable
or a non-prefetchable part of the bridge. We do not check to make
sure it is the right kind of memory because most drivers to not yet
properly set RF_PREFETCHABLE (only cardbus seems to do so, and I'm not
entirely sure it does it right). RF_PREFETCHABLE was invented for
cardbus, so hasn't been properly documented yet.
This is still overridable by hw.pci.allow_unsupported_io_ranges, but
the need for that is greatly reduced, especially for the nvida driver.

HP -> CPQ
Rearrange IDs to better match which chips they use.
Convert to uniform product description strings.
Simplify 7901A setup function.
Add the NONPACKFIFO_BUG and PACED_NEGTABLE_BUG entries
for the A.
Add rev B bugs and features.
The double write workaround for CURRSCB is only required if
abort pending is set. Remove this work around and set the
abort pending bug bit on the B at least until we have better
confirmation that the double write is always safe.
Add updated H2B identifiers
Move IOCell paramters into softc and add a hook for the
OSM to modify these as well as other settings prior to
committing them to the chip.
SLEW -> SLEWRATE
PREQDIS in DEVCONFIG1 went away after the A2.
Remove all code that references this bit. This
is especially important since this bit was reused
in the B for a different HW fix workaround.
Properly set the AHD_NEW_IOCELL_OPTS and
AHD_NEW_DFCNTRL_OPTS features for the B.
Remove stray/random extra 7901A generic PCI
table entry. Also switch the correct 7901A
generic entry to use ID_ALL_MASK since we
can only differentiate the 7901A from the
7902 by checking for a "type field" of 0xE.
Set AHD_INTCOLLISIONT_BUG for the Rev B.
Set the PREQDIS bit in DEVCONFIG1 for the B. The
bit is misnamed, but seems to disable a work-around
that breaks on the B on PCI busses.
Add a routine for testing memory mapped register access.
This will hopefully detect things like buggy via chipsets
so that the OSM can fallback to using I/O mapped access
when memory mapped I/O simply will not work.
