Ah ok, I see that things have changed a bit there ... well, we do have a
setup_paca(0) after the first DBG() so that should work.
Really, it's the kernel job to setup r13 before it has any use for it.
The kexec interface only specifies what is in r3..r5, everything else
can be 0xDEADBEEF as far as I'm concerned
