fca3465b96 Do not skip over a break trap instruction, now that the DDB code can 
do it properly.

9b3d64edb9 Remove the `segmap' array from the header. Insert an offset and count 
field to get to it instead.

Add field `kernbase' so libkvm can be independent of the kernel's link address.

1cd19dc013 Change crash dump layout a bit so the size of the `cpu_kcore' structure 
does not depend on the value of KERNBASE.

Change pmap_dumpsize() to return disk block units, in stead of pages.

1f1e574146 -implement a "device_register()" function to identify network interfaces 
by bus type / address (for diskless boot)
-add some (experimental, commented out) code which could be used for
 identification of boot disks - should help for BIOS remappings

610abce93b Copy data passed by the boot loader into an array "bootinfo". 
The former "cyloffset" argument is used as an (indirect) pointer to the
information structures. "cyloffset" has always been set to zero in the
past, so this should be save to do.

c03122fcb1 In some future (ie, without COMPAT_OLDBOOT), we don't want to bother 
with the disk type (IDE or SCSI) here - the BIOS doesn't do it either.
Set "#ifdef"s accordingly.

e0f973ee3b Implement the kernel part of pr-1891. This allows for a more flexible sized 
msgbuf. Note that old 'dmesg' and 'syslogd' binaries will continue running,
though old 'dmesg' binaries will output a few bytes of junk at the start of
the buffer, and will miss a few bytes at the end of the buffer.

a07bb333b1 Add an 800x600 Super72 mode; started by Neil Clark and finished by me. 
NOTE: due to hardware requirement of the AGA chipset, the framebuffer width
has to be a multiple of 64 bits.  An 800x600 display will use a memory width
of 832 bits, which the current X server can't handle.  To get a usable
display, the width needs to be 832 or 768.

9d1afc6f01 Fix a botch in reservemon4m() causing the `Alternate cacheability' not being 
set on viking MXCC machines while using transparent memory access mode. This
becomes apparent when booting on multi-processor viking machines.

While I'm here, arrange to tempt fate a little less by using `AC' mode
for the shortest possible periods of time.

Special thanks to Matt Ragan for running my test kernels.

c95e55b9ec Read the received data register before clearing the RBF interrupt. Clearing 
RBF appears to also clear the OVRUN bit in the receive data, resulting in
the loss of of overflow status.

0d05b5c280 Use the buffer length passed as a parameter to vmapbuf() and vunmapbuf() 
instead of bp->b_bcount.  The I/O operation may have changed bp->b_bcount,
and not all of the kernel virtual memory will be freed.  This will result
in the VM system putting pages back on the free list which are still
mapped.   This may cause a deadlock later trying to enter pages into
the kernel pmap.  [See PR#4120 for more details.]
