dc96bdaf1c Sync with sys/i386/boot/*/Makefile (Eivind's change: Make bootblock 
building independent of /usr/include if relative includes are
available).

354f83d34f TEMPORARILY disable support for the 4MB kernel page, as it appears to be 
causing installation images for -current to be unbootable.

338ca54caf Fixed an aliasing bug. It was too easy to defeat the check for moving 
or shrinking an open partition (by changing the label for a compatibility
slice while partitions on the corresponding real slice are open, or vice
versa).

9f24f214c3 Make the rootdir handling more consistent. Now, processes always 
have a root vnode associated with them, and no special checks for
the null case are needed.

a021db1639 - If a PCCARD serial device is removed from the system, let the serial 
driver 'break out' of the infinite loop waiting for a response from
  it.  This is a bad thing, but no worse than having the kernel hang.

a4daaa09f2 Implement the spirit but not the letter of Terrys hot-char patch. 
The differences Terrys patch and this patch are:
 * Remove a lot of un-needed comments.
 * Don't put l_hotchar at the front of stuct linesw, there is no need to.
 * Use the #defines for the hotchar in the SLIP and PPP line disciplines

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.
