unsuitable semantics. Define a MAX() macro unconditionally instead.
max() is unsuitable since we need a constant expression. Don't define
MIN() - we never used min().

pcaudio is active.
Update `time' before calling hardclock() when timer0 is being released.
This is not known to be important.
Added some delays in writertc(). Efficiency is not critical here, unlike
in rtcin(), and we already use conservative delays there.
Don't touch the hardware when machdep.i8254_freq is being changed but
the maximum count wouldn't change. This fixes jitter of up to 10 msec
for most small adjustments to machdep.i8254_freq. When the maximum
count needs to change, the hardware should be adjusted more carefully.
i386_set_ioperm(). Don't use a magic number for the bound.
Fixed missing bounds checking in i386_get_ioperm(). Don't use a
magic number for the bound elsewhere in this function.
Removed some bogus initializers.
this using option "-b" to the boot blocks. It is smartest to compile
a font into your kernel (See LINT), but not mandatory, but apart from
the cursor you will see nothing on the screen until you load a font.
This mode allows XF86_VGA16 to run in 800x600 mode on otherwise unsupported
graphics hardware.
A number of buglets in the cursor handling in syscons may become
visible this way.
actually faster (more than 20% faster for zeroing 1 MB at boot time).
This fixes pessimized copying and zeroing on K6's and perhaps on other
CPUs that are misclassified as i586's.
offset is non-zero:
- Do not match fragmented packets if the rule specifies a port or
TCP flags
- Match fragmented packets if the rule does not specify a port and
TCP flags
Since ipfw cannot examine port numbers or TCP flags for such packets,
it is now illegal to specify the 'frag' option with either ports or
tcpflags. Both kernel and ipfw userland utility will reject rules
containing a combination of these options.
BEWARE: packets that were previously passed may now be rejected, and
vice versa.

This means that a FreeBSD will only forward source routed packets

- A kludge: initialize scp->xpixel and ypixel even in the text mode.
If the console enters the `unknown' graphics mode via the ioctl KDSETMODE
(KD_GRAPHICS), these fields are not set (because syscons cannot know
the correct values), but set_mouse_pos() need to refer to these field
to adjust the mouse position.
- Turn off MOUSE_VISIBLE when switching video mode by ioctl.
- another new option: SC_MOUSE_CHAR
Define the first character code of four consecutive codes to be used for
the mouse cursor. Default codes are 0xd0 through 0xd3. Beware that
if you decide to use any codes outside the range of 0xc0-0xdf,
the mouse cursor may not look good, because of the way VGA displays
characters in 9-dot-wide character cells.

(This patch was tested by a person who recently reported, in the -current
ML, a page fault problem in the kernel (draw_mouse_iamge()) after
X server shutdown. The patch cured his problem.)

The reboot key (usually Ctl-Alt-Del) will be ignored if this option

it won't cause error when the keymap is loaded, but it will be quietly
treated as nop.
