I was unable to get /kernel.conf or /kernel.config to read in, so
I wasn't able to verify that this method of userconfig works. that's

o Add some kludges to maybe bring support for 1540A/1542A into the
driver. Since I have no 154xA cards, and the only person I know
that has them hasn't given me feedback, I'm making this commit
blind.
o Honor unit numbers that are in the config file now. This allows one
to hard wire the unit numbers (and have high unit numbers for plug
and pray devices, which can't seem to be hardwired) and have the
cards not migrate from aha1 -> aha0 should aha0 go on the fritz. I
didn't verify that hard wired scsi busses would work, but did verify
that hard wired aha addresses did work to a limited extent. Both
aha0 and aha1 must be hardwired, or when the card that was in aha0
goes away, the probe for aha0 might pick up the card that otherwise
would have been aha1.

Hopefully we can come to some conclusion about which Conner drives are
broken for tagged queueing.
The previous code just ignored the invalid map register, but this gave
surprising results because of the way pci_map_port() associated the map
register offset supplied with a map entry in the map array.

Also, fix the problem reported in PR kern/9482. The XPT_DEV_MATCH case in
xptioctl() wasn't putting a proper path in the CCB before it called
xpt_action(). When CAMDEBUG is defined, and CAM_DEBUG_TRACE debugging is
turned on, the CAM_DEBUG statement at the beginning of xpt_action would end
up deferencing a NULL path pointer. That of course caused a panic.
My solution is to just stick the xpt peripheral's path in the CCB.

Iprobe is an alpha-only system profiling suite which I'm porting from
Linux/alpha to FreeBSD.
Iprobe works by using the hardware profiling support built into
alpha cpus. In a nutshell, what Iprobe does is to setup the alpha
performance counters to sample the pc at a fairly high rate & dumps
those pc samples out to user space. Then some code runs to map the
sampled PCs to functions. You get a bit more than that (like the PSL
word, so you can tell if you're in the kernel or userland, what the
ipl is, etc).
o Add the EB64PLUS systype into the kernel configuration files
and add it to the GENERIC kernel
o Correct mcclock_isa.c's dependence on cia, it should depend on isa.
This will allow avanti and eb64+ kernels to be built without the cia
chipset support code.
The new file pci_eb64plus_intr.s deals with the interrupt hardware
on the EB64PLUS and was obtained from NetBSD with the NetBSD
copyright intact
The apecs chipset support code was altered to allow routing interrupts
through pci if we're not running on an avanti. Avanti's route all
interrupts through isa.

I don't _think_ this will hurt releases, aout-to-elf, etc, but it is
possible. In all the cases I've looked at, config(8) has been
generated straight after a make world, so if /usr/sbin/config exists and
is the right version for the kernel, then we can pretty much count on
/usr/bin/gensetdefs being there too.
XXX It probably makes sense to have a flag for bsd.kern.mk to avoid these

XXX IO_NDELAY seems to be the main reason for it, when used in a cdevsw

suggestions from Greg Lehey some time ago. In the face of multiple
potential file formats, try and give a more sensible error than just
ENOEXEC.
XXX a good case can be made that the loading process is wrong - the linker
should locate the file first (using the search paths etc), then run the
loaders to see if they recognize it. While the present system allows for
the possibility of different search paths for different formats, we do not
use it and it just makes things more complicated than they need to be.

to look up cookies properly, at least for standard controllers.
Cookies are used so that we don't have to pass around lots of args.
All of the dmainit functions use the unit number so it is essential
that we pass them a cookie with the correct unit number.
This may break working configurations if there are bugs in the
dmainit functions like the ones I just fixed for VIA chipsets.

Instead of initializing UDMA mode, we turned it off and made sure that
it stays off by turning on the "UDMA enable by SET FEATURES" disable.
The damage was limited by bugs in cookie lookup, and suitable
initialization by some BIOSes. The cookie list has slaves before
masters, and the unit number is ignored when cookies are looked up,
so cookie lookup always finds cookies for slaves and the bug only
clobbers slaves, so the bug was harmless for common configurations
with no slaves or only non-UDMA slaves. UDMA initialization for
masters actually worked if the BIOS turns on the UDMA mode bit and
turns off the "UDMA enable by SET FEATURES" disable.
