#     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.
#     
#     Fixes: 6a9c930bd775 ("powerpc/prom_init: Add the ESM call to prom_init")
