Sorry I'm a bit late to the thread, I've ben swamped. Has someone tested this
with kexec/kdump? Thats why the origional patch was created, because when kexec
loads the kernel at a different physical address, the relocations messed with
the module crc's, and modules couldn't load during the kexec boot. Assuming
that kernaddr_start gets set appropriately during boot, using PHYSICAL_START
should be fine, but I wanted to check, and don't currently have access to a
powerpc system to do so.
