        src/sys/arch/m68k/m68k: pmap_68k.c

Log Message:
pmap_changebit(): The CPUSHP is only necessary on the 68040/68060 if
the critical page attributes (W, CM) have changed; if we're just
clearning U or M, it can be skipped.

While here, simplify the initialization of proto-PTEs; PTE40_CM_WT == 0,
so we don't actually need a separate case for it that's distinct from the
non-PTE51_CI for the other MMUs variants.
