- Add a new PCIM_HDRTYPE constant for the field in PCIR_HDRTYPE that holds
the header type.
- Replace several magic numbers with appropriate constants for the header
type register and a couple of PCI_FUNCMAX.
- Merge to amd64 the fix to the i386 bridge code to skip devices with
unknown header types.

5.x signal code from the 4.x signal code. The split happened in
Oct 2002 and we have had 2 releases since then. A kernel older than
5.0-R cannot reasonably be called a -current kernel anymore.
This does not break upgrading from an 10 month older kernel. It just
makes it more exiting.
- Surround all accesses of the BKGRD{WAIT,INPROG} flags with the vnode
interlock.
- Don't use the B_LOCKED flag and QUEUE_LOCKED for background write
buffers. Check for the BKGRDINPROG flag before recycling or throwing
away a buffer. We do this instead because it is not safe for us to move
the original buffer to a new queue from the callback on the background
write buffer.
- Remove the B_LOCKED flag and the locked buffer queue. They are no longer
used.
- The vnode interlock is used around checks for BKGRDINPROG where it may
not be strictly necessary. If we hold the buf lock the a back-ground
write will not be started without our knowledge, one may only be
completed while we're not looking. Rather than remove the code, Document
two of the places where this extra locking is done. A pass should be
done to verify and minimize the locking later.
reading the CIS on some cards. However, not all just yet. This makes
at least some of the xircom cards that weren't working to work. It
doesn't make my home and away card work, however.
o Don't get the card offset wrong. This is the biggest hassle for
reading the CIS. The old code was just so wrong I can't believe that
it worked at all.
o Don't set the bit that allows/forces 16-bit memory access to the
memory. It is hard coded with 0x80.
o Don't need to slow down memory access with wait-states. OLDCARD didn't
need them and it doesn't hurt anything.
o remove bogus grousying in comment.
buildworld targets by default, but allow it to be done for all user
targets by introducing a boolean option, named ALWAYS_CHECK_MAKE.
This change is by no means perfect and I don't even want to claim
this to be a solution. It does however address the fact that not
everybody likes to see make(1) rebuilt simply because the regression
test failed for some reason or other, including pilot error. It
therefore serves the purpose of keeping the crowd happy until we
have something better or simply reached a compromise.
The reasons for changing the default behaviour are:
o It avoids a negative, possibly non-intuitive option,
o It's according to POLA and fond of feet,
o Only buildworld is documented to do its best to be
successful at reasonably cost.

32K pages are selected. In spec_getpages() change the printf format
specifier and add an explicit cast so that we always print the field
as a long type.
- In ULCK_BUF we no longer need to acquire the lock, just write the buf out.
- The combination of these changes eliminates one more use of B_LOCKED which
is in the way of making the buffer cache SMP safe. In the long term
ext2fs should probably not try to optimize the use of their metadata bufs
with a private cache. This will starve the rest of the system for buffers
in the extreme case.

METEORSSIGNAL ioctl. Applications use this ioctl with the value
METEOR_SIG_MODE_MASK (0xFFFF0000, -65536) to reset signal delivery,
but revision 1.126 caused the driver to return EINVAL in this case.
Interestingly, the same METEORSSIGNAL ioctl in the meteor driver uses
0 to reset signal delivery.
This commit allows METEOR_SIG_MODE_MASK as a synonym for 0 in the
bktr driver, and restructures the code a bit so that it is otherwise
identical between the bktr and meteor drivers.
returned mbuf can be NULL. Check for NULL in rip_output() when
prepending an IP header. This prevents mbuf exhaustion from
causing a local kernel panic when sending raw IP packets.
