cgd d6e5187749 add 'sd* at atapibus? drive ?' to all kernel configs already containing
an analogous line for 'cd'.

cgd 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.

drochner 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
  (changed to 0x340)

mrg 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.

tv 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.

thorpej 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.

fvdl 4357e617d2 When getting a pagefault for a PT page, wire it. Normally we fault them in
ourselves, but this can still happen on a 386 in copyout & friends.

Fixes pmap_changebit panics seen on 386s. Thanks to Juergen Hannken-Illjes
for providing detailed info on bug occurances.

bouyer 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".

thorpej 46c5ad921d Add a workaround for buggy i486 PCI chipsets that have trouble with
memory-mapped device access (manifested by an apparent wedging of the
PCI bus):
- If cpu_class == CPUCLASS_486, disable memory-mapped PCI device access,
  leaving only i/o-mapped access enabled.
- Provide a patchable kernel variable (i486_pci_mem_enabled) and a kernel
  option (I486_PCI_MEM_ENABLED) to re-enable it.

for a write fault on the illegal instruction descriptor.  Don't ask why this
works unless you have a strong stomach.
