    Subject[PATCH] x86: CONFIG_EFI should select CONFIG_RELOCATABLE
    EFI doesn't provide any guarantees that any given address will be free,
    so the bootloader must have the freedom to position the kernel
    appropriately. Make CONFIG_EFI select CONFIG_RELOCATABLE in order to
    ensure that this constraint is satisfiable.

    This enables the kernel to use EFI runtime services that are
    available (such as the EFI variable services).
