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.

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.

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.

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".

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.
