[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 Signed-off-by: Michael Ellerman <michael@ellerman.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org> 2005-12-04 18:39:37 +11:00			`#ifndef _PPC64_KDUMP_H`
