a3d6bdf148 New PS/2 mouse drive which uses the new 'shared' keyboard/psm read
routines.  An older version of this was tested successfully on all of my
systems with PS/2 mice.  This was brought in without testing because it
is necessary due to the previously committed syscons changes.

5cc90762ea Finally a start at sharing the kdb controller routines between
syscons and psm, curtesy Kazutaka Yokota with minor changes by
me. This contains an update of the psm driver as well.
This also fixes the breakage that I introduced to the psm driver by
making syscons poll for keyboard events in the atempt to fix the
hanging keyboard problem.

It works perfectly for me, and I'd like to hear from all that
have had keyboard/ps/2 mouse problems if this is the cure...

15ab0f62af Some more updates.
wdreg.h: Delete wd_ctlr macro.  PC98 version of wd.c treats it as a
variable.

GENERIC98: Delete ep0 entry. Current ep driver write I/O port 0x100.
This clobbers ICW of i8259, because upper 8bits of address line is not
masked on mother board.

if_fe.c: Merge from revision 1.18 of sys/i386/isa/if_fe.c.

pc98.c: Globalize dmapageport, because SCSI driver use this
variable.

wd82371.c: Yet another merge.

These are 2.2 candidates.

one too small for (hex) 12345678 and 4 too small for -1234567890.  Large
values can be created by config and userconfig although not (previously)

ee50e1f023 1. Avoid a race in scclose(). tty.c has kludges so that the race is
actually harmless.

2. Fixed code to match comment in scintr().

3. Don't allow even root to take control of the machine when securelevel > 0.
   I've secured the accesses to PSL_IOPL in all drivers and asked pst to
   review it, but he seems to be busy.  Write access to /dev/kmem and
   other critival devices currently leaks across raisings of securelevel
   via open fd's, so there may as well be a similar leak for PSL_IOPL.

4. (Most important.)  Don't corrupt memory beyond the screen buffers if
   the cursor happens to be off the 80x25 screen when syscons starts.

5. Fix console cursor update (not perfect yet).

2335bd9309 Replaced I586_OPTIMIZED_BCOPY and I586_OPTIMIZED_BZERO with boot-time
negative-logic flags (flags 0x01 and 0x02 for npx0, defaulting to unset = on).
This changes the default from off to on.  The options have been in current
for several months with no problems reported.

Added a boot-time negative-logic flag for the old I5886_FAST_BCOPY option
which went away too soon (flag 0x04 for npx0, defaulting to unset = on).

Added a boot-time way to set the memory size (iosiz in config, iosize in
userconfig for npx0).

LINT:
Removed old options.  Documented npx0's flags and iosiz.

options.i386:
Removed old options.

identcpu.c:
Don't set the function pointers here.  Setting them has to be delayed
until after userconfig has had a chance to disable them and until after
a good npx0 has been detected.

machdep.c:
Use npx0's iosize instead of MAXMEM if it is nonzero.

support.s:
Added vectors and glue code for copyin() and copyout().
Fixed ifdefs for i586_bzero().
Added ifdefs for i586_bcopy().

npx.c:
Set the function pointers here.
Clear hw_float when an npx exists but is too broken to use.
Restored style from a year or three ago in npxattach().

03be752913 Clean up the memory mapped/Programmed I/O stuff so that the driver completely
uses one or the other.  This required some changes to the ahc_reset()
function, and how early the probes had to allocate their softc.

Turn the AHC_IN/OUT* macros into inline functions and lowercase their names
to indicate this change.  Geting AHC_OUTSB to work as a macro doing
conditional memory mapped I/O would have been too gross.

Stop setting STPWEN in the main driver and let the PCI front end do it
instead.  It knows better.

Add the clearing of the QOUTQCNT variable during command complete processing
in the SCB paging case.

Go back to doing unconditional retries for the QUEUE FULL status condition.
This is really a kludge, but the code to handle it properly is on the SCSI
branch and will not make it into 2.2.

511b820d9d Don't switch from fast interrupt handlers to normal interrupt
handlers if interrupts are nested more than a few (3) deep.  This
only reduces the maximum nesting level by 1 with the standard
drivers unless there is a related bug somewhere, but can't hurt
much (the worst case is returning to hoggish interrupt handler like
wdintr(), but such interrupt handlers hurt anyway).

Fixed a previously harmless race incrementing the interrupt nesting
level.

fd95d6b479 Move the include opt_aic7xxx in aic7xxx.h so that all of the driver files get
it automatically.  The AHC_FORCE_PIO option wasn't having any effect because
the PCI probe code didn't include this file.

Fix some problems with the new sync and wide negotiation code.  First off,
go back to async transfers by using a message reject again.  The SCSI II and
III spec indicate that if a target's response to an initiater does not suit
(i.e. its too low), then performing a message reject is the appropriate
response.  If, on the other hand, the initiator begins the negotiation and
we want to go async, we will send back an SDTR message with a 0 period and
offset.

Also fix a really bad negotiation problem caused by a missing "break".  This
would usually hit people that had "smart" wide devices that immediately
attempt sync negotiation after a successful wide negotiation.

2.2 Candidate.
