I don't see anything wrong. Except flush_cpu_caches() should not even
flush 68040+ instr cache unless "force is set because CACR writes will
never flush 68040+ caches.

CPUSH and friends are needed which should be handled correctly and call
flush_cpu_caches() (from flush_cpu_caches_040()) if it also flushes
instr cache.
