I think this is KVM + CONFIG_RELOCATABLE. Caused by:

.global kvmppc_trampoline_lowmem
kvmppc_trampoline_lowmem:
	.long kvmppc_handler_lowmem_trampoline - CONFIG_KERNEL_START

.global kvmppc_trampoline_enter
kvmppc_trampoline_enter:
	.long kvmppc_handler_trampoline_enter - CONFIG_KERNEL_START

Alex, can you turn these into 64-bit on ppc64 so the relocator
can grok them ?

Cheers,
Ben.
