5883bcc9d2 Don't (conditionally) override the kernel's min() and max() functions
with macros.  This breaks if the functions are replaced by macros with
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().

1d804e7925 Update timer0_prescaler_count before calling hardclock() while timer0
is "acquired".  This fixes a TSC biasing error of about 10 msec when
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.

8a69c85a7e Add support for VESA mode 0x102 (800x600x4) in syscons. You can activate
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.

cd59d49d07 Only use the i586-optimized copying and zeroing functions if they are
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.

1ee1681798 - Move the mouse cursor to the center of the screen after video
mode switch in ioctl.
Possibly related to PR: kern/4271

- 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.
Requested by several people.

(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.)

59f5eaf466 - A new semaphore: font_loading_in_progress.
Don't touch/update the screen while manipulating font data.
Possibly related to PR: kern/4271

- Set up VGA in alphanumeric mode rather than graphics mode when
loading font into video memory. This will drastically reduce flicker.
PR: bin/2977

- Set up scp->font_size properly during video mode switch caused by
ioctl.

f8a35e9cef - Break scrn_timer() into two pieces. Now screen update is done in a
separate routine: scupdate() called from scrn_timer().

- Make sure that the screen is updated for the low-level console
routines sccngetc() and sccncheckc().  A new routine, sccnupdate(),
is introduced and will call scupdate() above.
Requested by: bde and msmith

4930cbfa04 - Ignore KBD_RAW_MODE and KBD_CODE_MODE in scgetc() when it's called
from the low-level console routines sccngetc() and sccncheckc().
Submitted by: bde (a long time ago)

- Don't try to ring bell and immediately return from do_bell() while
device probe is in progress at boot time; the timeout queue is not
functional yet.
PR: kern/2424

- Stop running the screen saver after panic() is called: check
if `panicstr' is non-NULL during scrn_timer().
PR: kern/5314

- A new option: SC_DISABLE_REBOOT
The reboot key (usually Ctl-Alt-Del) will be ignored if this option
is defined. You may still have the reboot key defined in the keymap and
it won't cause error when the keymap is loaded, but it will be quietly
treated as nop.

f1353e56ee If the kernel was built with USERCONFIG_BOOT, and the '-c' (RB_CONFIG) flag
was supplied to the kernel when booting, ignore any 'quit' commands in the
userconfig script.

This provides an escape mechanism whereby a broken userconfig script may
be worked around.

dad3b88ae3 In the words of the submitter:
----
I've worked to enhance the connect() patches.

I've just tested this with the Linux JDK appletviewer on an applet
that does a lot of connects, and it works as well as during my
previous tests.

The connect() patch is now a merge between my older patch and the
OpenBSD stuff. It ensures that any async error is returned by
connect() instead of getsockopt(SOL_SOCKET, SO_ERROR) as reasonnable
systems do.

There are also minor patches to implement IPPROTO_TCP for
get/setsocktopt(). These are also tested (with Linux Apache).
----

I would appreciate any feedback regarding these changes, as they'd
be very useful in 2.2.6.

95461b450d 1) Start using a cleaner and more consistant page allocator instead
of the various ad-hoc schemes.
2)	When bringing in UPAGES, the pmap code needs to do another vm_page_lookup.
3)	When appropriate, set the PG_A or PG_M bits a-priori to both avoid some
	processor errata, and to minimize redundant processor updating of page
	tables.
4)	Modify pmap_protect so that it can only remove permissions (as it
	originally supported.)  The additional capability is not needed.
5)	Streamline read-only to read-write page mappings.
6)	For pmap_copy_page, don't enable write mapping for source page.
7)	Correct and clean-up pmap_incore.
8)	Cluster initial kern_exec pagin.
9)	Removal of some minor lint from kern_malloc.
10)	Correct some ioopt code.
11)	Remove some dead code from the MI swapout routine.
12)	Correct vm_object_deallocate (to remove backing_object ref.)
13)	Fix dead object handling, that had problems under heavy memory load.
14)	Add minor vm_page_lookup improvements.
15)	Some pages are not in objects, and make sure that the vm_page.c can
	properly support such pages.
16)	Add some more page deficit handling.
17)	Some minor code readability improvements.

so that it is possible for kdump and truss to include them both.  Use
#defines from pcvt_ioctl.h in conflicting cases, since pcvt_ioctl.h
gives a hint about the bogus third arg to _IO().  Ifdef the common
typedefs.  Export `struct key_t' from pcvt_ioctl.h so pcvt_ioctl.h is
bug for bug compatible with console.h (now both are broken in C++
mode).
