[PATCH] powerpc: Reroute interrupts from 0 + offset to PHYSICAL_START + offset 2006-01-09T03:52:21+00:00 Michael Ellerman michael@ellerman.id.au 2005-12-04T07:39:37+00:00 0cc4746cadda16826a1b3214c042a2f75445b71c 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>
