point of not even compiling for a very long time.
Any effort spent unbreaking them would be better spent perfecting
the ata drivers for PC98, should any issues remain there.
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..

ACL configuration changes, this shouldn't result in different code paths
for file systems not explicitly configured for ACLs by the system
administrator. For UFS1, administrators must still recompile their
kernel to add support for extended attributes; for UFS2, it's sufficient
to enable ACLs using tunefs or at mount-time (tunefs preferred for
reliability reasons). UFS2, for a variety of reasons, including
performance and reliability, is the preferred file system for use with
ACLs.

NB: But it will enable it in all kernels not having options "NO_GEOM"
Put the GEOM related options into the intended order.
Add "options NO_GEOM" to all kernel configs apart from NOTES.
In some order of controlled fashion, the NO_GEOM options will be
removed, architecture by architecture in the coming days.
There are currently three known issues which may force people to
need the NO_GEOM option:
boot0cfg/fdisk:
Tries to update the MBR while it is being used to control
slices. GEOM does not allow this as a direct operation.
SCSI floppy drives:
Appearantly the scsi-da driver return "EBUSY" if no media
is inserted. This is wrong, it should return ENXIO.
PC98:
It is unclear if GEOM correctly recognizes all variants of
PC98 disklabels. (Help Wanted! I have neither docs nor HW)
These issues are all being worked.

This is an architecture that present a thing message passing interface
to the OS. You can query as to how many ports and what kind are attached
and enable them and so on.
A less grand view is that this is just another way to package SCSI (SPI or
FC) and FC-IP into a one-driver interface set.
This driver support the following hardware:
LSI FC909: Single channel, 1Gbps, Fibre Channel (FC-SCSI only)
LSI FC929: Dual Channel, 1-2Gbps, Fibre Channel (FC-SCSI only)
LSI 53c1020: Single Channel, Ultra4 (320M) (Untested)
LSI 53c1030: Dual Channel, Ultra4 (320M)
Currently it's in fair shape, but expect a lot of changes over the
next few weeks as it stabilizes.

The driver is mostly from some folks from Jeff Roberson's company- I've
been slowly migrating it to broader support that I it came to me as.
The hardware used in developing support came from:
FC909: LSI-Logic, Advansys (now Connetix)
FC929: LSI-Logic
53c1030: Antares Microsystems (they make a very fine board!)
MFC after: 3 weeks
and function) with existing configuration choices. Arguably if
ALT_BREAK_TO_DEBUGGER was present, so should have been
BREAK_TO_DEBUGGER. Regardless, it broke the option sort order in
these kernel configuration files.
