22c1670658 Some rearrangement of the startup code: 
* Move some of the memory bootstrapping and the DDB startup earlier.
* Always put the IDT and the initial GDT and LDT in a separate page.
* Various minor changes.

ad141a69a7 Shuffle wd/wdc driver files around (via repository copies). wdc 
now lives in dev/ic, wd now lives in dev/ata.  there's now a 'ata'
interface attribute defined in conf/files, but wdc can't go there
yet because some ports still use private versions based on the old
ISA version.

09354842c5 from Dave Burgess per PR4620: 
-base address 0x308 is supported by more Wangtek QIC tapes than 0x300
-Ultrastor ISA SCSI adapters can't be set to base address 0x334

057795048f this is the i386 MD portion of the MACHINE_NEW_NONCONTIG code, as 
written by chuck cranor.  thanks to mycroft for helping me find the
one little line of code i accidentally deleted while merging it.

this is not enabled by default.  `options MACHINE_NEW_NONCONTIG'
will use this code.  eventually, this should go into <machine/vmparam.h>
insteaed of MACHINE_NONCONTIG.

a7d1d15c39 KMEMSTATS is documented in options(4) as being a possible severe 
performance hit, and on an 80386 processor, it most certainly is.  Pull it
from the GENERIC (and DISKLESS "generic") kernels--configure it in
yourself if you actually need it.

b27ebeeac1 Work-around the situation where the buffer cache is larger than 
16M, thus eating up all candidate bounce pages, which are not allocated
until autoconfiguration runs, by deferring allocation of the buffer
cache pages until after autoconfiguration has run.

XXX This is safe because the i386 port doesn't read any disklabels
XXX during autoconfiguration.

4357e617d2 When getting a pagefault for a PT page, wire it. Normally we fault them in

d45f82208d Add a cpu_setup() function to "struct cpu_nocpuid_nameclass" and 
"struct cpu_cpuid_family", so that we can have a cpu_setup function per
known cpu type. For now use it only for cyrix 6x86 to enable suspend-on-halt
and implement cyrix's workaround to the "coma bug".
