address (apparently 0xff002000 in practice) which is not good if we need
to be able to map this to VA 0x1000. We could do it with pagetables but
a better solution seems to be to relocate the kernel in physical memory
before we start.
So, we copy the entire kernel image (code+data+bss) down to the 16MB
boundary that marks the start of RAM. This is slightly tricky because
we must not overwrite the copying code itself. :-) */
