- Set the correct value scp->font_size in init_scp().
- Set scp->font_size to FONT_NONE for VGA_MODEX.
Interim fix for a font problem:
- A kludge to display the correct font on some video cards.
We should be able to load multiple fonts to the VGA plane #2 and switch
between fonts by setting the font select register in the VGA sequencer.
It appears that the current code isn't functioning as expected on
some VGA cards (I have reports on Millenium and Mach64 cards). This is
either a bug in syscons or a hardware compatibility problem ;-<
This kludge will always load only one font set at a time and always use
the font page #0 on the plane #2. It is an interim kludge until
we find the exact cause and solution.
Small adjustment for mouse cursor handling:
- Turn off the mouse cursor early when changing video modes.
Video mode switch fixes:
- Stop the screen saver when changing video modes.
- Enclose the critical section with a pair of spltty()/splx().
- A kludge to prevent scrn_update() from accessing video memory in less-
critical sections in video mode change; artificially turn on the
UNKNOWN_MODE flag.

* Figure out UTC relative to boottime. Four new functions provide
time relative to boottime.
* move "runtime" into struct proc. This helps fix the calcru()
problem in SMP.
* kill mono_time.
* add timespec{add|sub|cmp} macros to time.h. (XXX: These may change!)
* nanosleep, select & poll takes long sleeps one day at a time

Tested by: ache and others
threads from invalid ones. The pthread structure is opaque to the user
so this change does not cause any incompatibilities.
Hopefully this change will help code that was written for draft 4
fail gracefully if the programmer ignores the compiler warning about
the change in the level of indirection for the argument passed to
pthread_detach(). I got burnt, so I fixed then (expletive deleted)
thing.
These functions comply with the revised standard. That should shut
Terry up!
Add a note about not touching errno and warn about previous drafts
of the standard which changed the level of indirection to the thread
argument. POSIX had a bit of trouble deciding what to do. So anyone
coding to both draft 4 and draft 10 (the final draft) will get burnt
by this function. I did. Grrr.
Explanation of the bug: when processing its first request, rarpd
opens a routing socket to send requests to the arp table. It keeps
that socket open afterwards, while waiting for new RARP requests.
Meanwhile, the data received on the routing socket fill up until
they are about 8Kbytes in size. Any additional data is lost.
When rarpd receives its next RARP request, it tries to access the
ARP table via a routing socket call, then waits for the answer to
its own request. This answer is lost because the received data is
already filled: when looking for the reply, rarpd receives only
8kbytes worth of data, then loops waiting forever.
Someone please test it on -STABLE and commit it. We can close the PR
when testing on STABLE is done.

- Attempt to handle PCI devices where the interrupt is
an ISA/EISA interrupt according to the mp table.
- Attempt to handle multiple IO APIC pins connected to
the same PCI or ISA/EISA interrupt source. Print a
warning if this happens, since performance is suboptimal.
This workaround is only used for PCI devices.
With these two workarounds, the -SMP kernel is capable of running on
my Asus P/I-P65UP5 motherboard when version 1.4 of the MP table is disabled.
