...for that matter weren't we tossing around the idea of just
making target_phys_addr_t 64 bits for everything? (I actually
want to do this for target-arm anyway; last time I did some
quick smoke-tests of performance it didn't seem to hurt really
even on a 32 bit host, and it avoids having to put the A15 in
a different qemu-system-* binary to the other cores.)
