The same goes for CD drivers and tape drivers. In systems with mixed IDE
and SCSI, devices in the same priority class will be sorted in attach
order.
Also, the 'CCD' priority is now the 'ARRAY' priority, and a number of
drivers have been modified to use that priority.
This includes the necessary changes to all drivers, except the ATA drivers.
Soren will modify those separately.
This does not include and does not require any change in the devstat
version number, since no known userland applications use the priority
enumerations.

Add MD_ROOT and MD_ROOT_SIZE options to the md driver.
Make the md driver handle MFS_ROOT and MFS_ROOT_SIZE options for compatibility.
Add md driver to GENERIC, PCCARD and LINT.
This is a cleanup which removes the need for some of the worse hacks in
MFS: We really want to have a rootvnode but MFS on a preloaded image
doesn't really have one. md is a true device, so it is less trouble.
This has been tested with make release, and if people remember to add
the "md" pseudo-device to their kernels, PicoBSD should be just fine
as well. If people have no other use for MFS, it can be removed from
the kernel.
- Convert to new bus attachment scheme. Thanks to Blaz Zupan for doing
the initial work here. One thing I changed was to have the attach
and detach routines work like the PCI drivers, which means that in
theory you should be able to load and unload the driver like the PCI
NIC drivers, however the pccard support for this hasn't settled down
yet so it doesn't quite work. Once the pccard work is done, I'll have
to revisit this.
- Add device wi0 to PCCARD. If we're lucky, people should be able to
install via their WaveLAN cards now.
- Add support for signal strength caching. The wicontrol utility has
also been updated to allow zeroing and displaying the signal strength
cache.
- Add a /sys/modules/wi directory and fix a Makefile to builf if_wi.ko.
Currently this module is only built for the i386 platform, though once
the pccard stuff is done it should be able to work on the alpha too.
(Theoretically you should be able to plug one of the WaveLAN/IEEE ISA
cards into an alpha with an ISA slot, but we'll see how that turns out.
- Update LINT to use only device wi0. There is no true ISA version of
the WaveLAN/IEEE so we'll never use an ISA attachment.

If the register is clobbered, it should be specified as an output as well,

if_fe.c uses PCCARD_MODULE() and is part of GENERIC. I've #ifdef'ed out
the #include of "card.h" to hopefully disable pccard support in this
driver until it can be converted. I'm not positive this will fix make
release, but it can't possibly make it any worse than it is now.
I hope this stuff settles down soon.
o Gut the compatibility interface, you now must attach with newbus.
o Unit numbers from pccardd are now ignored. This may change the units
assigned to a card. It now uses the first available unit.
o kill old skeleton code that is now obsolete.
o Use newbus attachment code.
o cleanup interfile dependencies some.
o kill list of devices per slot. we use the device tree for what we need.
o Remove now obsolete code.
o The ep driver (and maybe ed) may need some config file tweaks to
allow it to attach. See config files that were committed for examples
on how to do this.
Drivers to be commited shortly.
This is an interrum fix until the new pccard. ed, ep and sio will be
supported by me with this release, although others are welcome to try
to support other devices before new pccard is working.

when upgrading, since this code is known to work on my laptop and

o No devices actually have a pccard newbus attach in the tree.
BUGS THAT MIGHT BE FIXED:
o card removal, including suspend, usually hangs the system.

Reorganize the attachement point for pcic (it was unattached and
floating before). Attach pccard devices to pcic, one per slot
(although this may change to one per pcic). pcic is now attached to
isa (to act as a bridge) and pccard is attached to pcic, cbb and
pc98ic (the last two are card bus bridge and the pc98ic version of
pcic, neither of which are in the tree yet). Move pccard compat code
into pccard/pccard_compat.c.
THIS REQUIRES A CONFIG FILE CHANGE. You must change your pcic/card
entries to be:
# PCCARD (PCMCIA) support
controller pcic0 at isa?
controller pcic1 at isa?
controller card0
The old system was upside down and this corrects that problem. It
will make it easier to add support for YENTA pccard/card bus bridges.
Much more cleanup needs to happen before newbus devices can have
pccard attachments. My previous commit's comments were premature.

glibc2 defines struct dirent differently than the Linux kernel does.
The getdents function therefore needs to read a heuristically defined
number of kernel dirents to satisfy the request. In case where too
many kernel dirents have been read, the function lseeks on the
directory so that a next call will start with the right dirent. The
offset used in lseeking is the offset-field in the last dirent passed
to the application. This can only mean that the offset-field holds
the offset of the next dirent and not the offset of the dirent itself.
