a1c995b626 Last major round (Unless Bruce thinks of somthing :-) of malloc changes.
Distribute all but the most fundamental malloc types.  This time I also
remembered the trick to making things static:  Put "static" in front of
them.

02630e3d73 Allow "foo0: disabled, not probed" message to stay, but make it conditional
on bootverbose so that those who _really wanna know_ still can.

98823b2366 Convert the VM86 option from a global option to an option only depended
on by the files that use it.  Changing the VM86 option now only causes
a recompile of a dozen files or so rather than the entire kernel.

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.

6593be6011 Added two Cyrix 6x86/6x86MX options.
- CPU_CYRIX_NO_LOCK enables weak locking.  If this option is not set and
  FAILESAFE is defined, NO_LOCK bit of CCR1 is cleared.
- CPU_WT_ALLOC enables write-through allocation.

42c0de4926 It is possible that MB's with really broken bios's not set up more of
the mtrr registers.  This just fills in more of the registers.

c63ba9f5ae Make sure that the memory type registers are the same for each CPU
in a P6 SMP system.  Some MB bios'es don't set the registers up correctly
for the AP's.  Additionally, set the memory between 0xa0000 and 0xbffff
as write combining.

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.

fcc58b9423 Fix a bug where the speculative memory probe wouldn't occur on systems that
report slightly more than 64MB of total memory. This can happen due to the
total being the sum of both base and extended memory.

ca6e514c81 Turn on CR4_VME on the AP's the same as the BSP. Note that we do not
[yet] probe the AP's for their cpuid/capabilities etc, so this is a fudge

6ab4db67c0 For AMD chips, pick up the long description from the chip if
possible. (This is not really a typographical improvement in the
case of the K6 it seems, but AMD appearantly want it too look
that way).  Also if bootverbose, dump some more info about the
chip.

77509afdf3 teach pnp to keep isa_device structs around, and teach isa.c how to scan
these structs for conflics...

it still exist that two PnP cards can colide, but this is up to the user
to make sure it doesn't happen...

other modifications to pnp.c to format output properly, and hide more
output behind bootverbose flag...

fix some bugons in pnp.h that would of made it difficult for inclusion
in external programs (for import of pnpinfo)

421f9ee1ef Change an assemble-time divide into a shift. Under binutils-2.8 gas in elf
mode, the slash is a comment leader, while under non-elf it is a divide
symbol (what a concept! :-).  Theoretically, #APP/#NO_APP can change this
but that doesn't seem to mesh too well with macros and line continuation.

bb36094c06 Argh, what was I thinking?? Don't (yet) halt the CPU in the idle loop
while waiting for an interrupt (rather than spinning on the runqueue status
bits), since the other cpu can put stuff in there and the sleeping cpu may
not get an interrupt for a while.  When we have a reschedule IPI, this can
come back.

e91dd67ed8 Changed the memory sizing code so that if the following conditions
are met:

1) The BIOS indicates that there is exactly 64MB of RAM, and
2) The memory size isn't specified with the MAXMEM option or
   the npx0 msize hack,

   ...then do a speculative memory probe beyond the 64MB's until the
first bad page is encountered. This is an admitted hack, but should
nonetheless deal with detecting the correct amount of memory in nearly
all of the modern systems with >64MB of RAM.
Also made a change that will cause the list of detected memory chunks
to be printed if bootverbose is set.

2645264a72 Debug version of simple_lock. This will store the CPU id of the
holding CPU along with the lock.  When a CPU fails to get the lock
it compares its own id to the holder id.  If they are the same it
panic()s, as simple locks are binary, and this would cause a deadlock.

Controlled by smptests.h: SL_DEBUG, ON by default.

Some minor cleanup.
