        * include/grub/disk.h (grub_disk_dev_id): Add
        GRUB_DISK_DEVICE_RAID_ID and GRUB_DISK_DEVICE_LVM_ID.
        (grub_disk_get_size): New prototype.
        * kern/disk.c (grub_disk_open): Check whether grub_partition_probe()
        returns a partition.
        (grub_disk_get_size): New function.

        * kern/i386/pc/init.c (make_install_device): Copy the prefix
        verbatim if grub_install_dos_part is -2.

        * util/i386/pc/getroot.c (grub_guess_root_device): Support RAID
        and LVM devices.

        * util/i386/pc/grub-setup.c (setup): New argument
        MUST_EMBED. Force embedding of GRUB when the argument is
        true. Close FILE before returning.
        (main): Add support for RAID and LVM.

        * conf/common.rmk: Add RAID and LVM modules.
        * conf/i386-pc.rmk (grub_setup_SOURCES): Add util/raid.c and
        util/lvm.c.
