*  util/biosdisk.c (get_drive): Verify that `map[i].drive' is non-NULL
        before dereferencing it.

        * fs/fat.c (struct grub_fat_bpb): Move fat32-specific fields into a
        union with fat12/fat16-specific ones.  Add some new fields, including
        `num_serial' for both versions.
        (struct grub_fat_data): Add `uuid' member.
        (grub_fat_mount): Refer to fat32-specific fields in `bpb' by their new
        names.  Initialize `data->uuid' using `num_serial'.
        (grub_fat_uuid): New function.
        (grub_fat_fs): Reference grub_fat_uuid() in `uuid' struct member.

        * fs/reiserfs.c (grub_reiserfs_superblock): Add `uuid' field.
        (grub_reiserfs_uuid): New function.
        (grub_reiserfs_fs): Reference grub_reiserfs_uuid() in `uuid' struct
        member.

        * fs/xfs.c (grub_xfs_sblock): Add `uuid' field.
        (grub_xfs_uuid): New function.
        (grub_xfs_fs): Reference grub_reiserfs_uuid() in `uuid' struct member.
