Moving the interrupt vectors to low memory can cause issues if the code
gets overwritten via some image loading command (tftp, boot*, etc.) and
interrupts (like the decrementer are enabled).
On 85xx there is no reason to copy the interrupt vectors to low memory
since we can run them in high

Real, any reason why? I understand on classic PPC this might be the
case but I see no reason for it to be so on book-e parts.
Well, one reason might be to have

We want to free as much memory as possible. But low

Good point. Why don't we factor this out and make it common code for
all PPC?
Because the relocation is specific to the various interrupt types.

Umm... the exception code itself may be different, but does this imply
that the code used to copy / relocate the exception handlers to low
mem must be different, too?
