the ISA and CBUS (called isa on pc98) attachments. Eliminate all PC98
ifdefs in the process (the driver in pc98/pc98/mse.c was a copy of the one
in i386/isa/mse.c with PC98 ifdefs). Create a module for this driver.
I've tested this my PC-9821RaS40 with moused. I've not tested this on i386
because I have no InPort cards, or similar such things. NEC standardized
on bus mice very early, long before ps/2 mice ports apeared, so all PC-98
machines supported by FreeBSD/pc98 have bus mice, I believe.

"vm_fault: fault on nofault entry, addr: %lx" panic. The problem was a
stale PTE in the TLB that marked the page as not present, even though
we had a good PTE in the VHPT. We typically don't yet insert PTEs in
the TLB. We do that lazily. The CPU will look for the PTE in the VHPT
when there's no PTE in the TLB. Unfortunately this doesn't handle the
case of the stale PTE in the TLB. The quick fix is to invalidate the
TLB (sloppily) when the VHPT doesn't contain a valid PTE. This is also
the only case that may cause a PTE in the TLB that marks a page as
non-present.
four different locations on a prospective filesystem.
If we found none, we forgot to invalidate the four buffers, thus the
following sequence would fails:
(md0 = blank disk)
mount /dev/md0 /mnt
(fails, no superblocks)
newfs /dev/md0
(writes using physio which does not go through buffercache).
mount /dev/md0 /mnt
(still fails, the four cached buffers still contain no superblocks)

- The PCI data structure of some HME PROMs contains a non-zero interface
revision in the class code. Thus remove the checks for matching class
code and PCI data structure length and revsion. These were pretty much
useless anyway as we only really need the pointer to the VPD which is
located before the structure length and revision fields.
- On Sun QFE (Quad FastEthernet) cards read the Nth MAC-address for the
Nth HME controller instead of always the first one for all four HMEs. [1]
- Improve the comment describing the used VPD format to better reflect
reality.
- Minor clean-up.

First lets get major new features into the kernel in a clean and nice way,
and then start optimizing. In this case we don't have any obfusication that
makes later profiling and/or optimizing difficult in any way.

mechanism used by pfil. This shared locking mechanism will remove
a nasty lock order reversal which occurs when ucred based rules
are used which results in hard locks while mpsafenet=1.
So this removes the debug.mpsafenet=0 requirement when using
ucred based rules with IPFW.
It should be noted that this locking mechanism does not guarantee
fairness between read and write locks, and that it will favor
firewall chain readers over writers. This seemed acceptable since
write operations to firewall chains protected by this lock tend to
be less frequent than reads.
