a3adc4f8c5 Revert most changes of previous commit.
Changes relative to 1.12:
- Put extra instruction between outl()/inl() sequence to prevent the
  old value being read back because of the bus capacitance.
- Additional check for existence of register at CONF2_ENABLE_PORT.

0b4a1769be Our existing Cyrix cache-disable code was short-cutting the steps for
setting the control register.  Make the read and write operations two
completely separate steps.

While we're at it, pull in the whole set of Cyrix cache control options
from NetBSD-current,  since a few motherboards do the right thing with
the Cyrix chip.

There is no option to disable the internal cache completely (yet).

e21fd30049 When confronted with a drive that says there are 36 sectors/track,
ignore and set it to 18 sectors/track.  This allows FreeBSD to boot with
2.88MB floppies which are used in older ThinkPads.

97e112628f Check for page being resident when doing I/O with /dev/kmem and return
EFAULT if it is not resident. This prevents the system from manufacturing
a zero-fill page for unused but allocated areas of the kernel's VM. This
should fix the "CMAP busy" panic that some people saw during system
startup.

there is a PCI bus at all) ...

  requirements of the PCI 2.0 spec.

  sure that some other data have crossed the bus in between ...

0937c08c4e 1) Killed 'BSDVM_COMPAT'.
2) Killed i386pagesperpage as it is not used by anything.
3) Fixed benign miscalculations in pmap_bootstrap().
4) Moved allocation of ISA DMA memory to machdep.c.
5) Removed bogus vm_map_find()'s in pmap_init() - the entire range was
   already allocated kmem_init().
6) Added some comments.

virual_avail is still miscalculated NKPT*NBPG too large, but in order to
fix this properly requires moving the variable initialization into locore.s.

832e06d4dc From Bruce Evans: (prototype related changes, other cleanups)
Add prototypes.  Use static for function definitions to match existing
prototypes.  Otherwise leave functions that should be static as extern.
TODO: declare everthing except sidriver and siintr as static.  I use
some new cdevs registration functions to do this for syscons and pcvt.

Fix siintr() to match its prototype in ioconf.c (don't return anything).
This may break the eisa support, but Julian says that eisa interrupts
never worked anyway.

(EISA support was never tested anyway - Peter)

e7451974bb Make pcvt and syscons live in the same kernel. If both are enabled, then
the first one in the config has priority.  They can be switched using
userconfig().

i386/i386/conf.c:
Initialize the shared syscons/pcvt cdevsw entry to `nx'.

Add cdevsw registration functions.

Use devsw functions of the correct type if they exist.

i386/i386/cons.c:
Add renamed syscons entry points to constab.

i386/i386/cons.h:
Declare the renamed syscons entry points.

i386/i386/machdep.c:
Repeat console initialization after userconfig() in case the current
console has become wrong.  This depends on cn functions not wiring down
anything important.

sys/conf.h:
Declare new functions.

i386/isa/isa.[ch]:
Add a function to decide which display driver has priority.  Should be
done better.

i386/isa/syscons.c:
Rename pccn* -> sccn*.

Initialize CRTC start address in case the previous driver has moved it.

i386/isa/syscons.c, i386/isa/pcvt/*
Initialize the bogusly shared variable Crtat dynamically in case the
stored value was changed by the previous driver.

Initialize cdevsw table from a template.

Don't grab the console if another display driver has priority.

i386/isa/syscons.h, i386/isa/pcvt/pcvt_hdr.h:
Don't externally declare now-static cdevsw functions.

i386/isa/pcvt/pcvt_hdr.h:
Set the sensitive hardware flag so that pcvt doesn't always have lower
priority than syscons.  This also fixes the "stupid" detection of the
display after filling the display with text.

i386/isa/pcvt/pcvt_out.c:
Don't be confused the off-screen cursor offset 0xffff set by syscons.

kern/subr_xxx.c:
Add enough nxio/nodev/null devsw functions of the correct type for syscons
and pcvt.

f2cb5630d0 cons.c:
Split off cdevsw initialization in cninit() into a new function
cninit_finish() that isn't called until all hardware device drivers
have been attached.  The bdevsw entry of the driver for the physical
console needs to be hooked after the physical driver has been
attached in case the attachment modified the entry.

Rearrange cninit() to avoid changing cn_tab until the driver for the
physical console has been initialized, so that the previous driver
(if any) can be used for debugging.

Start removing half-baked lint support.  bdevsw functions usually have
unused args but /*ARGSUSED*/ was used for only about 5% of them.

cons.h:
Declare cn_init_finish().

autoconf.c:
Call cn_init_finish().

Start adding prototypes.  Functions with bogus linkage (extern where
static is probably should be static) are explicitly declared as extern
so that the can be found easily (extern in a non-header is usually
wrong).

All:
Continue cleaning up init stuff: init functions shall be static;
INITs should be at the start of files...

2bf07b2bd7 Patch to the atapi driver, by Serge V.Vakulenko, minor changes
by me...

Original message:

This patch upgrades the ATAPI CD-ROM driver to version 1.3.

It has three bugs fixed:

1) The `controller not ready' message at startup and later.
   It was caused by staled media change bit.

2) Incorrect shuffling of model string for some drives (NEC, Mitsumi).

3) Handling of drives which report itself as been of direct-access type,
   instead of CD-ROM type.

There is one known bug which is not fixed yet -- probing
in absense of IDE disks. A work-around exists though (thanks Steve!).
If you have no IDE disks attached, then remove them from the kernel
config file to make the CD-ROM attach correctly.
Unfortunately, there is no way to disable them from the kernel
interactive config mode.

67f06b6142 Clean up a few nits in the aic7xxx driver:
1) Make the driver "quiet" by sticking most boot messages behind
	bootverbose conditionals.  This means that you won't see the
	sync and wide negotiation, but you will find out if they fail.

2) Add support to the 93cx6 serial eeprom code to read at an abitrary
	offset.  This is needed so that we can access the second half
	of the eeprom on 3940 cards where the second channel's config
	is stored.

3) Add flags argument to ahcprobe().  This is used by the pci probe code
	to tell the generic driver that an adapter should be treated
	as a channel B device as well as notify it of the presence of
	external SCB SRAM.  These are needed for some motherboard
	implementations of the aic7870 and for the 3940 controllers.

4) Print "Channel A"/"Channel B" instead of "Single Channel" for the
	two busses of the 3940.  I received many reports of confusion
	about how the 3940 was probed since most people belived that
	only one ahc entry was needed.  This will hopefully make it
	clearer.

5) Walk the SCBs to determine just how many their are if external SCB
	ram is detected.

6) Hard code that external SCB ram is present for the 3940 since it doesn't
	use the documented reporting facility for reporting the SRAM. :(
	255 commands per channel are supported on the 3940.

7) Read the seeprom starting at addres 32 for the second channel of the
	3940 so we get the right info for that channel.

8) Clean up printing of the "Disabling tagged queuing message".

9) Queue timeouts if they occur while we are handling a timeout.  The code
	was totally unprotected in this scenario.
