old type (stty) ioctls can easily bypass locking bits.
It involves manual conversion from old ioctls to new ones,
large piece of code duplicated from tty_compat.c
after ttioctl too, because it can change t_line.
Remove (TS_CNTTB | TS_LNCH) test, it is always inherits from
old tty mode and can't be reach in currently setted mode.
update what has actually been touched. This should speed up
screen access on slow hardware.
Introduced setting of "destructive" cursor size, much like
the old hardware cursor.
if (tp->t_line != 0)
test when CS_ODONE, it fails for NTTYDISC, use
if (linesw[tp->t_line].l_start != ttstart)
instead.

BREAK/parity/framing errors.
Term "correctly" assumes POSIX spec. and 4.4 ttyinput() behaviour.
1) Discard BREAK/parity at interrupt level when apropriate IGN*
is set in iflag. It helps "raw" mode works even IGN* is set.
2) Zero parity (if INPCK) and framing directly in buffer
before passing it to b_to_q() in "raw" mode.
Efficency:
interrupt level: if no error occurse, only two "test" commands added
"raw" mode: buf scan incc times for parity/framing added

Made CTRL-space generate nul as default.
(a) bring back ttselect, now that we have xxxdevtotty() it isn't dangerous.

utilities don't crash if NAPM changes (and make the damn kernel compile!)
(d) rewrite /dev/snp ioctl interface so that it is device driver and i386

Removed screensavers from syscons, they are now LKM's. This makes it
possible to do some really "interesting" screensavers...
Fixed bug that sometimes caused garbage to appear when leaving
"scroll-lock" history.
Reformattet indentation, it got too deep for a normal 80 pos screen.
Split up in syscons.c & syscons.h for use with the saver-lkm's.
Temporarily removed -s option from vidcontrol, savers should now
be loaded with modload.
briefly over it, and see some serious architectural issues in this stuff.
On the other hand, I doubt that we will have any solution to these issues
before 2.1, so we might as well leave this in.
Most of the stuff is bracketed by #ifdef's so it shouldn't matter too much
in the normal case.

raw things (what hardware do for us, exactly) as default case,
all driver features must be _optional_. Modern VGAs have internal
configuration utilities to set cursor shape/blinking which stored
into cards ROM, and syscons nuke out such features completely
by forcing software cursor. Moreover, software cursor is hard
to distinguish on standouted (or near standouted) fields and
tends to disappearse from the screen.
Set "flags 0x4" to enable software cursor now.

o Don't draw cursor if saver or blinker is active.

sio.c and sioreg.c changed to allow autodetecting the RB_SERIAL flag
passed by the boot blocks so that the kernel can switch to 'serial
console' mode automagically. 'options COMCONSOLE' can still be specified
to force the kernel to always use the serial port as a console.
CONUNIT and CONADDR can also be specified in the kernel config file
if the user wants to shift the console to a different port.
Put in the much shorter and cleaner version for the calibrate_cycle_counter

Use bcopyw() instead of move_up() and move_down(). bcopyw() handles
overlapped copies and should be faster. Actually use bcopy(). bcopy()
is slightly faster if video memory is 16-bit and about twice as fast if
it is 32-bit. bcopy() is said to fail on someGA's, but syscons already
depends on it working for other accesses to video memory.
- /sys/i386/isa/if_ed.c doesn't quite know how to deal with SMC EtherEZ
ethernet cards. The EtherEZ looks just like the Elite Ultra, except it
has only 8K of shared memory. The only way to have it properly detected
is to zero and test a few bytes of memory just about the first 8K region.
If it clears properly, it's an Elite Ultra, otherwise it's an EtherEZ.
I've also got an EtherEZ patch for netboot (Makefile, ether.c and ether.h).
- /sys/i386/isa/syscons.c wraps at the next to the last column rather than
the last column, like it should. You don't really notice this unless you
use certain programs that write all the way out to, say, the 80th column,
like VMSmail. Along with a one-line fix for this are some changes to
implement a non-blinking cursor. Put 'options "NOBLINK_CURSOR"' in your
config file and give it a try. :)

Move definition of `stat_imask' to clock.c.

Rename `rtcmask' to `stat_imask' and export it. Rename `clkmask' to
`clk_imask' for consistency.
Only calculate TIMER_DIV(hz) once.
Merge debugging and "garbage" code to produce debugging code and format the
output better.
Make writertc() static inline and use it everywhere. Now all accesses to

Move rtc initialization to cpu_initclocks().
Merge enablertclock() with cpu_initclocks() and remove enablertclock().

Rename `timer0_prescale' to `timer0_prescaler_count' and maintain it

only lose a few cycles for every standard clock interrupt.
Rename `*_divisor' to `*_max_count'.
Do the calculation of TIMER_DIV(rate) only once instead of 3 times each
time the rate is changed.
Don't allow preposterously large interrupt rates. Bug fixes elsewhere
should allow the system to survive rates that saturate the system, however.

Include <machine/clock.h> to check our own declarations.
