The use of the 'kernel_offset' variable to position the image file that has been loaded by UEFI or GRUB is unnecessary, because we can directly position the loaded image file through using the image_base field of the efi_loaded_image struct provided by UEFI. Replace kernel_offset with image_base to position the image file that has been loaded by UEFI or GRUB. Signed-off-by: Wang Yao <wangyao@lemote.com> Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
