af2f22807f Fixed write enabling of the kernel text section. The overlap
checking was mostly wrong at the boundaries.  For the lower limit,
VM_MIN_KERNEL_ADDRESS was used instead of btext and there was an
off-by-(`size' - 1) error.  For the upper limit, &etext was used
instead of etext and there was an off-by-1 error.  The bugs were
harmless because `size' is not too large and some memory is mapped
just beyond the ends.  We still depend on the former to avoid
having to handle the case where the memory range covers the whole
text section, and on the latter to prevent problems when we map
just beyond an end to allow writing an address range that overlaps
the end.

Fixed placement of a nearby comment.

e6af3c69e8 Don't allow setting the dump device to any partition except the
one traditionally reserved for swap devices.  The restrictions
should now be the same as the ones for dumpsys().  The restriction
on the partition should be removed someday, and dumpsys() shouldn't
repeat all the checks.

8fa40736f6 Don't #include <machine/smp.h> even in the SMP case. Fixed the one
place that depended on it.  The "bazillion warnings" mentioned in the
log for rev.1.45 apparently aren't a problem any more.  It is hard
to be sure because the SIMPLELOCK_DEBUG option turns off (and breaks)
things in the SMP case.

cb226aaa62 Move the "retval" (3rd) parameter from all syscall functions and put
it in struct proc instead.

This fixes a boatload of compiler warning, and removes a lot of cruft
from the sources.

I have not removed the /*ARGSUSED*/, they will require some looking at.

libkvm, ps and other userland struct proc frobbing programs will need
recompiled.

e7e437dbfa - Do a bunch of gratuitous changes intended to make the code easier to
follow.
 * Rename/reorder all of the pccard structures, change many of the member
   names to be descriptive, and follow more closely other 'bus' drivers
   naming schemes.
 * Rename a bunch of parameter and local variable names to be more
   consistant in the code.
 * Renamed the PCCARD 'crd' device to be the 'card' device
 * KNF and make the code consistant where it was obvious.
 * ifdef'd out some unused code

9e5fbad43e - Enable PS/2 mouse support by default. Given that almost all new hardware
has a PS/2 port, this is a good thing.  Note, older 386/486 boxes may
  lockup the keyboard controller with this enabled, but most of these kinds
  of machines don't run -current, so the benefits outweigh the downsides.

643b3d0cf2 Fix a serious bug I introduced while adding in support for CAM interrupts.
It seems I didn't count my 0's properly when adding the new masks into
icu_vector.s pushing SWI_AST_MASK off the end of the array and screwing
up the indexing for SWI_CLOCK_MASK.

Fix the bug icu_vector.s and also reformat the code in both icu_vector.s and
apic_vector.s so that it will be much harder to make the same mistake in
the future.

a2575e01e8 Add a small hack to support the strange antics of the Unisys ELI 4003. This
machine generates an NMI for each floating point error, just like an old XT.
Since it is ISA only, reading the EISA status port yields 0xff, which would
give a spurious EISA panic.  The simplest thing to do is to ignore the 0xff.
