Hi Neil,

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. Neil

I tested a relocatable kernel forced to run at a non zero physical
address (ie basically kdump). I verified CRCs were bad with your
original patch backed out, and were good with this patch applied.
