docs don't seem to shed light on why this is needed, but reports from
the field indicate this helps prevent problems in this area. Ken's
changes seem to have exposed this bug, rather than caused it, as far
as I can tell.
Thanks to Jack O'Neill for tracking this down.

Very strong 3.2 merge candidate.
It never makes sense to specify MAP_COPY_NEEDED without also specifying
MAP_COPY_ON_WRITE, and vice versa. Thus, MAP_COPY_ON_WRITE suffices.

instances to a parent bus.
* Define a new method BUS_ADD_CHILD which can be called from DEVICE_IDENTIFY
to add new instances.
* Add a generic implementation of DEVICE_PROBE which calls DEVICE_IDENTIFY
for each driver attached to the parent's devclass.
* Move the hint-based isa probe from the isa driver to a new isahint driver
which can be shared between i386 and alpha.
Sync up device Ids with the master Adaptec list.
Add probe support for the 2940 Pro although it isn't obvious that
all of the termination support is correct for this adapter yet.
tell the sequencer to pause itself for a target msg variable update. This
avoids the pause race entirely as HS_MAILBOX can be accessed without
pausing the chip.

v1.19 (1999/04/15) updates the CEM56/REM56 support.
Current bugs & misfeatures
--------------------------
* CE2 cards still not working reliably. Unclear if this is related to
packet I/O code or interrupt handling.
* Autonegotiation support remains flaky. We're now OK with 10Mbit auto
hubs, but certain combination of hardware will fail to connect.

v1.17 (1999/03/28) has xperimental fixes to 10Mbit autonegotiation and
CE2 input lockup.
KNOWN BUGS
==========
* Media auto-negotiation is definitely not right. It will work in most
circumstances and seems to connect OK to most 100Mbit networks, however some
pathological combinations of hubs/networks/peers seem to confuse it.
* CE2 support is somewhat flakey (ranging from 'works perfectly' to 'hangs the
machine' so far). I've fixed the probe routine and a potential lockup in
the output routine, but a lot of people still report that they can't receive
or transmit.
* You won't be able to use the modem and Ethenet parts of a multifunction card
simultaneously. This is limitation the current FreeBSD PCMCIA support.
Likewise, there is no support for CardBus devices.

This driver is mostly based on the `xirc2ps' driver for Linux by Werner
Koch. Werner has even allowed his code to be distributed under a BSD licence,
making our life considerably easier -- thanks Werner!
This driver supports:
* Intel EtherExpress(TM) PRO/100 PCCARD (16-bit version)
* Xircom CreditCard CE2 / CEM28 / CEM33 / CE3 / CEM56 Ethernet adapters.
* Toshiba Advanced Network 10/100 PCCARD
* Certain Compaq Netelligent 10/100 branded cards
v1.14 has major changes to media selection code, and bugfixes in the
probe routine.

inodes were synced every 15 seconds. This is now reversed as during
directory create, we cannot commit the directory entry until its
inode has been written. With this switch, the inodes will be more
likely to be written by the time that the directory is written thus
reducing the number of directory rollbacks that are needed.
