Fixed style bugs in the moved code. Fixed everything that depended on
the nested include. Don't include <machine/cpu.h> (in the changed files)

use a Linker Set. Note, if a driver is loaded as an LKM if will have
to use the function call, but since none of the existing drivers
are loadable, this made things cleaner and boot messages nicer.

* Kill individual drivers 'suspend' routines, since there's no simple/safe
way to suspend/resume a card w/out going through the complete probe
at initialization time.
* Default to using the apm_pccard_resume sysctl code, which basically
pretends the card was removed, and then re-inserted. Suspend/resume
is now 'emulated' with a fake insert/removal. (Hence we no longer
need the driver-specific suspend routines.)

* 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

* Renamed the PCCARD 'crd' device to be the 'card' device

- Move the configuration option SC_HISTORY_SIZE from syscons.h to
syscons.c.
- Define the maximum total number of history lines of all consoles.
It is SC_HISTORY_SIZE*MAXCONS or 1000*MAXCONS; whichever is larger.
CONS_HISTORY will allow the user to set the history size up to
SC_HISTORY_SIZE unconditionally (or the current height of the console
if it is larger than SC_HISTORY_SIZE). If the user requests a larger
buffer, it will be granted only if the total number of all allocated
history lines and the requested number of lines won't exceed the maximum.
- Don't free the previous history buffer and leave the history buffer
pointer holding a invalid pointer. Set the pointer to NULL first, then
free the buffer.

floppy drive #0, regardless of what the CMOS says. This is intended
as a bandaid for those plagued with Compaq's idea to not announce the
floppy drive on their `Aero' notebook.
Using the device flags is not very nice (in particular since they
aren't per-drive but per-controller), but still looks a lot better to
me than the disgusting guesswork hack that was recently posted to
-hackers.
Doc update will follow shortly.
Distribute all but the most fundamental malloc types. This time I also

them.

also document that if you set the PnP flags (pnp x flags y) to 0x1 that

is for people that want the traditional isa driver to probe and attach

As a side effect, broken enhanced floppy controllers that sometimes
don't detect dma overruns/underruns will give less errors.

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.

There is now another simple_lock around clock data/hardware accesses in
clock.c and microtime.s. It is my belief that this is the only area
sio/cy might stumble into during an unblocked INTerrupt. Thus I separated
the sio/cy code from the generic disable_intr()/enable_intr() routines.
Controlled by smptests.h: USE_COMLOCK, ON by default.
Add a simplelock to deal with disable_intr()/enable_intr() as used in UP kernel.
UP kernel expects that this is enough to guarantee exclusive access to
regions of code bracketed by these 2 functions.
Add a simplelock to bracket clock accesses in clock.c: clock_lock.

Made NEW_STRATEGY default.
Removed misc. old cruft.
Centralized simple locks into mp_machdep.c
Centralized simple lock macros into param.h
More cleanup in the direction of making splxx()/cpl MP-safe.
Several new fine-grained locks.
New FAST_INTR() methods:
- separate simplelock for FAST_INTR, no more giant lock.
- FAST_INTR()s no longer checks ipending on way out of ISR.
sio made MP-safe (I hope).
Add support for MODEX 320x240x256color with "unchained" adressing, giving
access to all 256K on all VGA's, those with that much memory that is :)
Also make sysmouse use the right resolution in graphics modes.
- removed TEST_ALTTIMER.
- removed APIC_PIN0_TIMER.
- removed TIMER_ALL.
apic_vector.s:
- new algorithm where a CPU uses try_mplock instead of get_mplock:
if successful continue as before.
if fail set ipending bit, mask INT (to avoid recursion), cleanup & iret.
This allows the CPU to return to successful work, while the ISR will be run
by the CPU holding the lock as part of the doreti dance.
