Clean up the handling of failure modes in our attach so we don't free
resources twice. ahc_free() will do all of the work for us (as would
be required by an unload event) so we only need to handle resources that
the softc has not taken ownership of.
Fixed problems:
LS120 drives currupted data.
The workaround for drives not supporting upto 64K transfers
has been reworked. It works now both on LS120 & ZIP drives.
ISA only configs wont compile.
Fixed.
The ATA driver wont share interrupts.
Fixed.
The "unwanted interrupt" warning gave wrong controller.
Another lun<>unit messup from the newbus integration.
Some minor cleanups and rearrangements as well.
As usual USE AT YOUR OWN RISK!!, this is still pre alpha level code.
Especially the DMA support can hose your disk real bad if anything
goes wrong, again you have been warned :)
Notebook owners should be carefull that their machines dont suspend
as this might cause trouble...
But please tell me how it works for you!
Enjoy!

Change reference count in struct ifaddr to a u_int, to be able
to handle more than 2^16 routes to the same interface.
Fix suggested by Andrew Bangs <andrewb@demon.net> in PR kern/10570.
Tested by <adrian@freebsd.org> and me under -current.
Remove a useless argument from vm_map_madvise's interface (vm_map.c,
vm_map.h, and vm_mmap.c).
Remove a redundant test in vm_uiomove (vm_map.c).
Make two changes to vm_object_coalesce:
1. Determine whether the new range of pages actually overlaps
the existing object's range of pages before calling vm_object_page_remove.
(Prior to this change almost 90% of the calls to vm_object_page_remove
were to remove pages that were beyond the end of the object.)
2. Free any swap space allocated to removed pages.
though, on systems (386 mostly) that still have a seperate fpu, but it
might be possible to find systems where the FPU coprocessor is wired to
a different IRQ pin.
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.

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.

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.

Changed to `const void *'. utrace() is undocumented, so nothing should
notice.
Fixed missing consts for utrace() and ktrace() in syscalls.master.
sys/ktrace.h is missing some Lite2 changes of shorts to ints.
with malloc type at the tail of the list changed the list from
linear to circular. This seemed to cause surprisingly few problems,
but it now causes weird output from `vmstat -m', probably because
a more important malloc type is now at the tail of the list.
Fix it by abusing ks_limit instead of ks_next as a flag for being
on the list. Don't forget to clear the flag when a malloc type is
uninit'ed. Uninit'ing is still fundamentally broken -- it loses
history.
udev_t in the kernel but still called dev_t in userland.
Provide functions to manipulate both types:
major() umajor()
minor() uminor()
makedev() umakedev()
dev2udev() udev2dev()
For now they're functions, they will become in-line functions
after one of the next two steps in this process.
Return major/minor/makedev to macro-hood for userland.
Register a name in cdevsw[] for the "filedescriptor" driver.
In the kernel the udev_t appears in places where we have the
major/minor number combination, (ie: a potential device: we
may not have the driver nor the device), like in inodes, vattr,
cdevsw registration and so on, whereas the dev_t appears where
we carry around a reference to a actual device.
In the future the cdevsw and the aliased-from vnode will be hung
directly from the dev_t, along with up to two softc pointers for
the device driver and a few houskeeping bits. This will essentially
replace the current "alias" check code (same buck, bigger bang).
A little stunt has been provided to try to catch places where the
wrong type is being used (dev_t vs udev_t), if you see something
not working, #undef DEVT_FASCIST in kern/kern_conf.c and see if
it makes a difference. If it does, please try to track it down
(many hands make light work) or at least try to reproduce it
as simply as possible, and describe how to do that.
Without DEVT_FASCIST I belive this patch is a no-op.
Stylistic/posixoid comments about the userland view of the <sys/*.h>
files welcome now, from userland they now contain the end result.
Next planned step: make all dev_t's refer to the same devsw[] which
means convert BLK's to CHR's at the perimeter of the vnodes and
other places where they enter the game (bootdev, mknod, sysctl).
Use colons instead of semi-colons in the default init_path to behave like
UNIX instead of DOS.

bad math: it does not handle page-boundary conditions, and will not
end up mapping all of the requested addresses. This will cause a panic:
page fault during probe on some systems. I have a machine that will
panic every time (when using the dpt driver) on kernel probe when there
are 5 drives installed. When there are 4 drives, it is fine.
Fix is to always allocate/deallocate an extra page.
There is also a bonus splx() fix on an early error return.
