scheme of things, so I've changed them to be more appropriate. page in/ous
are now associated with the pager that did them. Nuked v_fault as the
only fault of interest that wouldn't be already counted in v_trap is a VM
fault, and this is counted seperately.
2) Implemented most of the remaining counters and corrected the counting of
some that were done wrong. They are all almost correct now...just a few
minor ones left to fix.
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).

This is the main files for the iBCS2 emulator. It can be use
compiled into the kernel by using:
options IBCS2
options COMPAT_IBCS2
or as a lkm module using:
options COMPAT_IBCS2
and then loading it via the ibcs2 script in /usr/bin
REMEMBER: this code is still experimental ! NO WARRENTY !

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 ! ***
"APM" macro.
machdep.c: Made the APM-descriptors unconditional.
Bruce: if these still conflict with your debugger, please put in a reservation
for your debugger. These three desc. can be anywhere, as long as they are
contiguous, so just move them as needed.
pmap.c: tons of unused vars zapped, various other warnings silenced.
trap.c: unused vars zapped.
vm_machdep.c: A wrong argument, which by chance did the right thing, was
corrected.
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.
