e871e61fcf Addition of support of the slightly rogue Promise IDE interface(Dyson), support
of multiple PCI IDE controllers(Dyson), and some updates and cleanups from
John Hood, who originally made our IDE DMA stuff work :-).

I have run tests with 7 IDE drives connected to my system, all in DMA
mode, with no errors.  Modulo any bugs, this stuff makes IDE look
really good (within it's limitations.)

ab71361364 Adjust the #ifdef KERNEL so that pnp_cinfo is available for sbin/dset.c
Other ways around this might be to #define KERNEL in dset.c for the
"i386/isa/pnp.h" include.

6a796ce0a1 teach sio how to attach to isa PnP cards. This is mainly for use with
internal modems.  Currently detects a USR modem, and a couple Supra
modems...  vendor id's for sio capabile cards welcomed...

document new option EXTRA_SIO that will increase sio's internal data
structures to support X more serial ports...  these are used by the
PnP part of sio for attaching...  If you don't have it specified, it
will default to 2...  This is defaulted to 0 if you don't have PnP
compiled into your kernel...

also document that if you set the PnP flags (pnp x flags y) to 0x1 that
the modem will be refused to be recognized by the sio driver... this
is for people that want the traditional isa driver to probe and attach
the modem... (for keeping legacy sio numbering)

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)

d66c374f58 Enable the FIFO on enhanced floppy controllers. This reduces the
number of dma overruns/underruns for systems under heavy dma load.
As a side effect, broken enhanced floppy controllers that sometimes
don't detect dma overruns/underruns will give less errors.

d2fb48929a Make FDC_DEBUG a supported option.
Hide the bogus FDC ``chip type'' display behind a (mostly) undocumented
option, since people started to trust the bogus claim.  Once we're going
to handle 2.88 MB controllers, we have to redo the chip detection, by
now just leave it hidden.

acb902182f Fix the broken VT_WAITACTIVE ioctl for the case where the third arg
was 0.

PR:		4164
Submitted by:	Joe Traister <traister@mojozone.org>

While i was at it, also fixed a broken return value for the VT_RELDISP
ioctl, iff the third arg was legally VT_TRUE, but the destination
screen was in process mode so the actual switch had to be deferred.
This was breaking the ability to directly toggle between two X servers
running on two VTs, since the server getting the bogus error return
was running wild, and competing with the other one for the hardware.
(Sigh, this was a very long-standing bug.)

ffdd472de7 Allow a compile-time override of the ipfw deny rule. For a 'firewall'
you don't want this (and the documentation explains why), but if you
use ipfw as an as-needed casual filter as needed which normally runs as
'allow all' then having the kernel and /sbin/ipfw get out of sync is a
*MAJOR* pain in the behind.

2daf730067 add the plug-and-play code into current...
This code has been submitted by Luigi Rizzo <luigi@labinfo.iet.unipi.it>,
based on work done by Sujal Patel.

This currnetly doesn't provide the ability to register the port address
of PnP cards assigned a PnP driver.  As there aren't any PnP capible
drivers yet, this isn't much of a problem.

The code allows you, through USERCONFIG, configure what the cards port
bases, irqs, and dma's are like.  Currently there isn't support to view
what cards are in the sytem.

It successfully configures my PnP Internal Modem and sio then sees the
card as a normal isa device.

man page will be committed shortly.

6514ad5540 Turn on the 0WS option for 16bit cards. Newer machines insert enough
delay that without this the performance is unacceptable. The 83C690,
83C790, and 83C795 chips which this affects are all designed to work
with 0 waitstates in 16bit mode.
Also cleaned up the toggling of 16bit access mode that occurs during
normal operation; the previous code may not have done the right thing
in all cases.

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.

Kazutaka YOKOTA
9d6218d088 Add a new compile option SC_HISTORY_SIZE to specify the history buffer
size in terms of lines (instead of bytes).  When changing video mode
in ioctl SW_XXX commands, syscons checks scp->history_size and
allocate a history buffer at least as large as the new screen size.
(This was unnecessary before, because HISTORY_SIZE was as large as 100
lines and this is bigger than the maximum screen size: 60 lines).
Similar adjustment is done in ioctl CONS_HISTORY command too.

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.
