Change the second argument of vflush() to an integer that specifies
the number of references on the filesystem root vnode to be both
expected and released. Many filesystems hold an extra reference on
the filesystem root vnode, which must be accounted for when
determining if the filesystem is busy and then released if it isn't
busy. The old `skipvp' approach required individual filesystem
xxx_unmount functions to re-implement much of vflush()'s logic to
deal with the root vnode.
All 9 filesystems that hold an extra reference on the root vnode
got the logic wrong in the case of forced unmounts, so `umount -f'
would always fail if there were any extra root vnode references.
Fix this issue centrally in vflush(), now that we can.
This commit also fixes a vnode reference leak in devfs, which could
result in idle devfs filesystems that refuse to unmount.

Adjust the descriptor structures a little by making the software parts

a multiple of 8 bytes in size, since the 83820/83821 chips require

read transfer latency and simplifies testing for transfer
complete (check SCSIEN only). We also disable the expected
phase feature, and enable the new bus free interrupt behavior,
to avoid a few instructions.
Re-arrange the Ultra2+ data phase handling to allow us to

Add battery state monitoring to apmd.
The new syntax available in the config file is:

The stuff in the braces is the same as the existing case. nn% checks for
a certain percentage of life remaining and nnM checks for a cerain
number of minutes remaining. Specifying "discharge" means that you're
interested in knowing when the battery reaches a certain level while AC
power is off, "charging" the opposite.
The man page needs to be updated.
The code can be fooled. If you SIGHUP the daemon and the battery level
matches a rule it will be performed once per SIGHUP. If the battery
level matches a rule and you repeatedly apply and take away AC power,
the rule will be run once per occurance. This, however, is a feature.
:-) The code also only runs when select() times out, so getting APM
events more often than the timeout interval will result in the rules not
being run. These are things that remain to be overcome.

Fix the so called "static bug" in polling mode. Some desktop cards
have bad grounding characteristics which allow small static discharges
(or sunspots, we're not 100% sure which) to reach the bridge chip.
This causes the bridge chip to wedge/reset itself. There's no known
cure short of rebooting.
The bug manifests itself by the STAT_CHG return 0xff when read. This
is impossible because the upper bits are reserved (and therefore
zero). In addition, some of the lower bits are one only for memory
cards, which OLDCARD doesn't support, so if they are set, something
seriously foobar'd is going on.
So far we've seen this in exactly one brand of pcmcia <-> isa bridge
which plug and play identifies only as "VIA PCMCIA CARD". This card
just has buffers on the isa card and the actual bridge chip on the
remote slot, which is connected by long ribbon cables. We think this
long cable run, coupled with the lack of coupling capacitors is a
major reason why it is so static sensitive while its bretheren aren't.
