protection checks. Using the partition-relative blkno in some
parts broke the write protection for partitions at unusual
offsets (only for partitions at offset 1 on i386's).
several new features are added:
- support vc/vp shaping
- support pvc shadow interface
code cleanup:
- remove WMAYBE related code. ENI WMAYBE DMA doen't work.
- remove updating if_lastchange for every packet.
- BPF related code is moved to midway.c as it should be.
(bpfwrite should work if atm_pseudohdr and LLC/SNAP are
prepended.)
- BPF link type is changed to DLT_ATM_RFC1483.
BPF now understands only LLC/SNAP!! (because bpf can't
handle variable link header length.)
It is recommended to use LLC/SNAP instead of NULL
encapsulation for various reasons. (BPF, IPv6,
interoperability, etc.)
the code has been used for months in ALTQ and KAME IPv6.
OKed by phk long time ago.
best place to set it, and the wd and wfd strategy routines don't
set it (for failed transfers) because they expect dscheck() to
initialize everything necessary. dscheck() has always set B_ERROR,
but this is not quite sufficient, because b_resid is used by physio()
to decide how much of a B_ERROR'ed i/o was done.
formats and args to match. Fixed old printf format errors (all related;
most were hidden by calling printf indirectly).
This change somehow avoids compiler bugs for 64-bit longs on i386's,
although it increases the number of 64-bit calculations.
fork_trampoline() if switchtime is valid. This fixes not accounting
for the time between the previous context switch and and the current
time (when the forked child starts up here) in most cases - the time
is now counted in the child's runtime. I think it actually fixes
all cases, and switchtime is always valid here, since there must have
been a context switch just before the forked child starts up. Some
code should be removed if this is correct. The check that switchtime
is valid sometimes gives a false negative because the check isn't
correct until the after the first context switch after the system
has been up for >= 1 second.
The machine can not recognize this PD drive
as neither PD drive nor CD-ROM Drive.
So I can not use CD-ROMs and PDs from FreeBSD.

Reimplement pmap_remove() to be much more efficient at removing large
stretches of addresses.
As part of reimplementing pmap_remove() fix pmap_protect() so that it stands
a hope of working.
Change the port address argument to pci_map_port to pci_port_t* which is
defined as u_int on the alpha, u_short on i386. This is a stopgap with a
hopefully limited lifetime.
