#     powerpc/prom_init: Undo relocation before entering secure mode
#     
#     The ultravisor will do an integrity check of the kernel image but we
#     relocated it so the check will fail. Restore the original image by
#     relocating it back to the kernel virtual base address.
#     
#     This works because during build vmlinux is linked with an expected
#     virtual runtime address of KERNELBASE.
#
