Revision/Branch: netbsd-1-2

Modified Files:
        locore.s 
Log Message:
Fix a bug in the 68020+68851 / 68030 branch of the buserr handler:

For these CPU's, you have to use the ptest operation to search the mmu
tables in order to decide whether it is a real bus error or just a
page fault or write protection violation.

Our old code assumed user space always when calling ptest, and
erroneously assumed the BUSERR bit in the ptest output (mmusr
register) is the only indication for bus errors to check.

In fact, we have to follow a multistage decision tree to decide. 68060
CPUs are much easier to handle correctly.

Log Message:
get rid of now-unnecessary kernel config files (now that swap generic
works) for my machines and now-nonexistent test machines.  Clean up
options in existing config files so that they're more consistent.  Add
more units of various pseudo-devices to several.
