changes to the VM system to support the new swapper, VM bug
fixes, several VM optimizations, and some additional revamping of the
VM code. The specific bug fixes will be documented with additional
forced commits. This commit is somewhat rough in regards to code
cleanup issues.

pnp system in freebsd, I'm not sure how useful this will be, but my
1542CP seems to work well in plug and play mode and does seem to
probe correctly at all the oddball addresses/irq/drqs that I tried.
[[
I was unable to get /kernel.conf or /kernel.config to read in, so
I wasn't able to verify that this method of userconfig works. that's
one thing that makes pnp so hard to use in the current scheme.
Pointers to the right new way of doing this accepted.

o Add some kludges to maybe bring support for 1540A/1542A into the
driver. Since I have no 154xA cards, and the only person I know
that has them hasn't given me feedback, I'm making this commit
blind.
o Honor unit numbers that are in the config file now. This allows one
to hard wire the unit numbers (and have high unit numbers for plug
and pray devices, which can't seem to be hardwired) and have the
cards not migrate from aha1 -> aha0 should aha0 go on the fritz. I
didn't verify that hard wired scsi busses would work, but did verify
that hard wired aha addresses did work to a limited extent. Both
aha0 and aha1 must be hardwired, or when the card that was in aha0
goes away, the probe for aha0 might pick up the card that otherwise
would have been aha1.

I don't _think_ this will hurt releases, aout-to-elf, etc, but it is
possible. In all the cases I've looked at, config(8) has been
generated straight after a make world, so if /usr/sbin/config exists and
is the right version for the kernel, then we can pretty much count on
/usr/bin/gensetdefs being there too.
to look up cookies properly, at least for standard controllers.
Cookies are used so that we don't have to pass around lots of args.
All of the dmainit functions use the unit number so it is essential
that we pass them a cookie with the correct unit number.
This may break working configurations if there are bugs in the
dmainit functions like the ones I just fixed for VIA chipsets.

IDE hardare. The attempted fix in rev.1.182 was a no-op except for
adding dozens of style bugs. The undocumented options ALI_V and
DISABLE_PCI_IDE go away as a side effect. ALI_V was a no-op because
rev.1.182 was a no-op. DISABLE_PCI_IDE didn't actually disable
PCI IDE. It disabled the buggy code in wdprobe() at a cost of
completely breaking support for Promise controllers.

if option CY_PCI_FASTINTR is configured and mapping the irq to a

pci_map_int_right() doesn't handle the INTR_EXCL flag right --
INTR_EXCL is honoured even if the interrupt needs to be non-exclusive

buffer had to be left on the head of the queue for [bufq]disksort()
to sort against. This isn't right for devices that can support multiple
active i/o's, and only the fd driver did it. "Fixing" this in rev.1.36
of ufs_disksubr.c broke the fd driver in much the same way as rev.1.52

Because of the changes, you are required to update your kernel
configuration file now!
The files in sys/dev/syscons are still i386-specific (but less so than
before), and won't compile for alpha and PC98 yet.
syscons still directly accesses the video card registers here and
there; this will be rectified in the later stages.

There is not point in loading gobs of ascii into the kernel when

Next thing we'd be adding all section 4 man pages to the loaded

The argument about KLD's is bogus, klds can store a file in
/usr/share/doc/sysctl/dev/foo/thisvar.txt with a description and
sysctl or other facilities can pick it up there.
Proper documentation will take several K worth of text for many
sysctl variables, we don't want that in the kernel under any
circumstances.
I will welcome any well thought out attempt at improving the
situation wrt. sysctl documentation, but this wasn't it.

For now, the only board that I know of that uses this chip is the
Alfa Inc. GFC2204. (Its predecessor, the GFC2202, was a DEC tulip card.)
Thanks again to Ulf for obtaining the board for me. If anyone runs
across another, please feel free to update the man page and/or the
release notes. (The same applies for the other drivers.)
FreeBSD should now have support for all of the DEC tulip workalike
chipsets currently on the market (Macronix, Lite-On, Winbond, ASIX).
And unless I'm mistaken, it should also have support for all PCI fast
ethernet chipsets in general (except maybe the SMC FEAST chip, which
nobody seems to ever use, including SMC). Now if only we could convince
3Com, Intel or whoever to cough up some documentation for gigabit
ethernet hardware.
Also updated RELNOTEX.TXT to mention that the SVEC PN102TX is supported
by the Macronix driver (assuming you actually have an SVEC PN102TX with
a Macronix chip on it; I tried to order a PN102TX once and got a box
labeled 'Hawking Technology PN102TX' that had a VIA Rhine board inside
it).

RB_CONFIG.
Now, the code should do the right thing in the following cases, when
kernel is compiled with INTRO_USERCONFIG:
* when booted without userconfig_script and without RB_CONFIG, present
intro screen, and wait for user input.
* when booted with userconfig_script and without RB_CONFIG, DON'T present
intro screen unless explicitly asked in userconfig_script, basing on
assumption that if a user loads userconfig_script, (s)he already
decided what parameters to configure. Proceed with booting.
* when booted without userconfig_script, and with RB_CONFIG, enter
configuration utility and wait for user input.
* when booted with userconfig_script, and with RB_CONFIG, execute all
commands from userconfig_script, and DON'T leave the config utility,
but wait for user input.
And finally, regardless of the combination of the above parameters,
when intro screen is invoked either first or next times, and user
chooses to go back to CLI interface, unblock the quit command.
On a system with a large amount of ram (e.g. 2G), allocation of per-page
data structures (512K physical pages) could easily bust the initial kernel
page table (36M), and growth of kernel page table requires kptobj.
