[PATCH] powerpc: Reroute interrupts from 0 + offset to PHYSICAL_START + offset
Regardless of where the kernel's linked we always get interrupts at low
addresses. This patch creates a trampoline in the first 3 pages of memory,
where interrupts land, and patches those addresses to jump into the real
kernel code at PHYSICAL_START.
We also need to reserve the trampoline code and a bit more in prom.c
