Document the options available for the ata driver.
Disconnect the atapi devices from the old wd driver to avoid conflicts
(they will go away at some point anyways)
continue doing it despite objections by me (the principal author).
Note that this doesn't fix the real problem -- the real problem is generally
bad setup by ignorant users, and education is the right way to fix it.
So while this doesn't actually solve the prolem mentioned in the complaint
(since it's still possible to do it via other methods, although they mostly
involve a bit more complicity), and there are better methods to do this,
nobody was willing or able to provide me with a real world example that
couldn't be worked around using the existing permissions and group
mechanism. And therefore, security by removing features is the method of
the day.
I only had three applications that used it, in any event. One of them would
have made debugging easier, but I still haven't finished it, and won't
now, so it doesn't really matter.
* GC unused options
* Move options that exist on all architectures to conf/options
* Add missing options to LINT
* Sort undocumented options list in LINT

Fix a bug which could cause panics in ad/atapi-interrupt.
Add support for UDMA66 on Promise Ultra/Fasttrak controllers.
Get rid of ATA_IGNORE_INTR, and introduce ATA_WAIT_INTR instead.

seem to need this. Also dont use the timeout watchdog when dumping.

We currently only search SCSI and IDE CDROMs; if there's felt to be a
need for supporting the very old and rare soundcard etc. drives for this
application they can be trivially added.
the soft updates changes: only report the link count to be i_effnlink
in ufs_getattr() for file systems that maintain i_effnlink.

In order to achieve this, root filesystem mount is moved from
SI_ORDER_FIRST to SI_ORDER_SECOND in the SI_SUB_MOUNT_ROOT sysinit
group. Now, modules which wish to usurp the default root mount
can use SI_ORDER_FIRST.
A compiled-in or preloaded MFS filesystem will become the root
filesystem unless the vfs.root.mountfrom environment variable refers
to a valid bootable device. This will normally only be the case when
the kernel and MFS image have been loaded from a disk which has a
valid /etc/fstab file. In this case, the variable should be manually
overridden in the loader, or the kernel booted with -a. In either
case "mfs:" should be supplied as the new value.
Also fix a typo in one DFLTROOT case that would not have compiled.
