I think that this has nothing to do with the error. The pv code is there to
facilitate creating a single binary kernel on ARM. Kernel still has constant
PHYS_OFFSET but we patch v<->p instructions runtime to make the kernel adapt
with the load address.

So having correct PHYS_OFFSET should be enough.
