Use a new pa_to_va() macro for all BIOS and video addresses in syscons.
and all SCSI devices (except that it's not done quite the way I want). New
information added includes:
- A text description of the device
- A ``state''---unknown, unconfigured, idle, or busy
- A generic parent device (with support in the m.i. code)
- An interrupt mask type field (which will hopefully go away) so that

This requires a new version of the `lsdev' program as well (next commit).
so i hope i've finally removed all the occasions where the driver
got stuck when there's no floppy in the drive.

for the first time, since people tend to be confused about this.
else has been probed. This feature could go away again, if we can curb the
problem another way.
if_ed.c, syscons.c: Set the above flag. ed# because it needs it, syscons
because it looks stupid to "detect" the display you have already filled up
with text :-)
bt742a.c: Check bt_cmd() return-val during probe, thus failing on adaptec's.
Also silenced various printf's during the probe.
isa.c: Probe devices with the above flag set before the rest. Reduce the
number of "conflict" messages per device to one.

of mb_offset given the right sequence of 1 and 0 byte mbufs. This bug
was discovered by John Hood who also provided this fix - which is a
rewrite of the routine (and is easier to understand than the code I wrote).

Fix endless loop in siopoll() for an event on a tty with no tty struct.
Don't generate unwanted interrupts in the serial console driver. These
bugs probably don't matter unless the tty struct is dynamically allocated.
Support polled mode. To use it, leave out the irq and the vector in
the config file. It only causes extra overhead for open polled ports.
The maximum usable speed is approximately 1000 bps for a 16450 and
15000 bps for a 16550.
Other cosmetic changes.
Bug fixed, that caused system hang on first interrupt on some motherboards.
New version of PCI bus configuration code, now supports dynamic interrupt
configuration (using BIOS supplied values).
NCR SCSI and DEC Ethernet driver patched to use this feature.
*** Remove PCI IRQ specifications from your kernel config file ! ***
the first place was so that BPF could grok trailer packets. I've since
decided that this is a job for tcpdump to decipher (if at all). Also
fixed up checks for received packet length to better cope with ancient
starlan boards.
be merged at some point)
New AMD family ethernet driver. Should support BICC,NE2100, TNIC,
AT1500 and anything else that uses a Lance/PCnet type chip. Only been
tested with the BICC so far though.
Still work to do on performance and MULTICAST support needs to be added
but it's basically working and I want the revision history from this
point on

New version with improved support for WIDE SCSI using the NCR 53c825.
Test for buggy secondary cache implementations.
PCI Int to IRQ mapping now specified per slot.
This is needed for having the fdformat program no longer searching
non-public include paths.
Protect the definitions in fdreg.h against double inclusion.
more work required to grab all fonts
2)Make standard VGA font as default, make HARDFONTS an option
(load iso8859 fonts instead)
3)Check fonts_loaded for all restore (copy_font...palette)
sequences.
when the drive had been left on a cylinder > 67 after kernel boot. The
most common case for this is booting a kernel that is located on
the inner cylinders of a floppy.
Also removed all occurences of spinwait(), replaced by DELAY.
Nuked a return line saying nothing, this might make Bruce happy 8^)
