Since qemu does not implement the L2 cache, we get stuck forever waiting for a bit to be set when trying to invalidate it. To prevent that, we should bail out if the L2 cache is missing. One easy way to check this is L2CFG0 == 0 (since L2CSIZE always has at least one bit set in a valid implementation) (tested on qemu, rb800, and x5000) Reviewed by: jhibbits Sponsored by: Tag1 Consulting, Inc.
