* There is now 2 structures, preloaded_elf32_image and preloaded_elf64_image, which both inherit from preloaded_image. * For now I've just hardcoded in use of preloaded_elf32_image, but the bootloader ELF code will shortly be converted to use templates which use the appropriate structure. The kernel will be changed later when I add ELF64 support to it. * All kernel_args data is now compatible between 32-bit and 64-bit kernels.
