* disk/memdisk.c (memdisk_size): Don't initialize.
        (GRUB_MOD_INIT(memdisk)): Find memdisk using grub_module_iterate().

        * include/grub/i386/pc/kernel.h
        (GRUB_KERNEL_MACHINE_MEMDISK_IMAGE_SIZE): Remove macro.
        (GRUB_KERNEL_MACHINE_PREFIX, GRUB_KERNEL_MACHINE_DATA_END): Shift.
        (grub_memdisk_image_size, grub_arch_memdisk_addr)
        (grub_arch_memdisk_size): Remove.

        * include/grub/kernel.h (struct grub_module_header): Remove `offset'
        field (was only used to transfer a constant).  Add `type' field to
        support multiple module types.
        (grub_module_iterate): New function.

        * kern/device.c (grub_device_open): Do not hide error messages
        when grub_disk_open() fails.  Use grub_print_error() instead.

        * kern/i386/pc/init.c (grub_arch_modules_addr)
        (grub_arch_memdisk_size): Remove functions.
        (grub_arch_modules_addr): Return the module address in high memory
        (now that it isn't copied anymore).

        * kern/i386/pc/startup.S (grub_memdisk_image_size): Remove variable.
        (codestart): Don't add grub_memdisk_image_size to %ecx in LZMA
        decompression routine (grub_total_module_size already includes that
        now).  Don't copy modules back to low memory.

        * kern/main.c: Include `<grub/mm.h>'.
        (grub_load_modules): Split out (and use) ...
        (grub_module_iterate): ... this function, which iterates through
        module objects and runs a hook.
        Comment out grub_mm_init_region() call, as it would cause non-ELF
        modules to be overwritten.

        * util/i386/pc/grub-mkimage.c (generate_image): Instead of appending
        the memdisk image in its own region, make it part of the module list.
        * util/elf/grub-mkimage.c (options): Add "memdisk"|'m' option.
        (main): Parse --memdisk|-m option, and pass user-provided path as
        parameter to generate_image().
        (add_segments): Pass `memdisk_path' down to load_modules().
        (load_modules): Embed memdisk image in module section when requested.
        * util/i386/efi/grub-mkimage.c (make_mods_section): Initialize
        `header.type' instead of `header.offset'.

        * conf/powerpc-ieee1275.rmk (pkglib_MODULES): Add `memdisk.mod'.
        (memdisk_mod_SOURCES, memdisk_mod_CFLAGS)
        (memdisk_mod_LDFLAGS): New variables.
        * conf/i386-coreboot.rmk: Likewise.
        * conf/i386-ieee1275.rmk: Likewise.
