* 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.
* disk/ata.c (grub_ata_open): Don't lose precision in disk->id.
* disk/host.c (grub_host_open): Likewise.
* disk/loopback.c (grub_loopback_open): Likewise.
* disk/memdisk.c (grub_memdisk_open): Use a string pointer for
disk->id as in disk/host.c, not a multi-character constant.
* conf/i386-pc.rmk (kernel_img_HEADERS): Add `machine/kernel.h'.
(pkglib_MODULES): Add `memdisk.mod'.
(memdisk_mod_SOURCES): New variable.
(memdisk_mod_CFLAGS): Likewise.
(memdisk_mod_LDFLAGS): Likewise.
* disk/memdisk.c: New file.
* include/grub/disk.h (grub_disk_dev_id): Add
`GRUB_DISK_DEVICE_MEMDISK_ID'.
* include/grub/i386/pc/kernel.h
(GRUB_KERNEL_MACHINE_MEMDISK_IMAGE_SIZE): New macro.
(GRUB_KERNEL_MACHINE_PREFIX): Increment by 4.
(grub_kernel_image_size): New variable declaration.
(grub_total_module_size): Likewise.
(grub_memdisk_image_size): Likewise.
* include/grub/i386/pc/memory.h
(GRUB_MEMORY_MACHINE_DECOMPRESSION_ADDR): New macro.
* include/grub/kernel.h: Include `<grub/symbol.h>'.
(grub_arch_memdisk_addr): New variable declaration.
(grub_arch_memdisk_size): Likewise.
* kern/i386/pc/init.c (grub_arch_memdisk_addr): New function.
(grub_arch_memdisk_size): Likewise.
* kern/i386/pc/startup.S (grub_memdisk_image_size): New variable.
(codestart): Replace hardcoded `0x100000' with
`GRUB_MEMORY_MACHINE_DECOMPRESSION_ADDR' macro.
* util/i386/pc/grub-mkimage.c: Include `<grub/misc.h>'.
(generate_image): Add `memdisk_path' parameter. When `memdisk_path' is
not NULL, append the contents of the file it refers to, at the end of
the compressed kernel image. Initialize `grub_memdisk_image_size'
variable (at `GRUB_KERNEL_MACHINE_MEMDISK_IMAGE_SIZE' offset).
(options): Add "memdisk"|'m' option.
(main): Parse --memdisk|-m option, and pass user-provided path as
parameter to generate_image().
