* fs/fshelp.c (grub_fshelp_read): New function. Implement
linear disk read with journal translation.
* fs/ext2.c: Use grub_fshelp_read() instead of grub_disk_read().
* include/grub/fshelp.h: Declare grub_fshelp_read().
Based on description from Pavel:
* kern/disk.c (grub_disk_check_range): Rename to ...
(grub_disk_adjust_range): ... this. Add a comment explaining the
tasks performed by this function.
* util/biosdisk.c (open_device): Revert last change to the
function, it broke installation. The sector needs to be
different dependent on which device is opened.
Ensure GRUB_KERNEL_MACHINE_DATA_END is always consistent with the
rest of GRUB, and breakage doesn't happen if its value were modified.
* include/grub/i386/pc/kernel.h (GRUB_KERNEL_MACHINE_RAW_SIZE):
Redefine as an offset from `GRUB_KERNEL_MACHINE_DATA_END' instead of
a constant (same value).
* kern/i386/pc/startup.S: Replace hardcoded `0x50' with
`GRUB_KERNEL_MACHINE_DATA_END' (same value).
* util/grub-emu.c (grub_machine_init): Move code in this function from
here ...
(main): ... to here (before grub_util_biosdisk_init() call, to prevent
segfault in case grub_printf() is called).
* util/i386/pc/grub-install.in: Append `--device-map=${device_map}' to
grub_probe. Update all users not to explicitly add it again.
(grub_device): New variable; contains corresponding device for grubdir.

`--device ${grub_device}' to grub_probe to avoid traversing /dev
every time.
* 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'.

* fs/reiserfs.c (grub_reiserfs_superblock): Add `uuid' field.

member.

(grub_xfs_fs): Reference grub_reiserfs_uuid() in `uuid' struct member.
* disk/i386/pc/biosdisk.c (grub_biosdisk_iterate): Iterate through
floppies after everything else, to ensure floppy drive isn't accessed
unnecessarily (patch from Bean).
* term/ieee1275/ofconsole.c (grub_ofconsole_setcursor): Implement
using "cursor-on" and "cursor-off" commands (understood at least by
the Open Firmware flavour on OLPC).
* util/biosdisk.c (linux_find_partition): Simplify logic and
make the code more universal. Keep special processing for
devfs, but use a simple rule for all other devices. If the
device ends with a number, append 'p' and the partition number.
Otherwise, append only the partition number.
* util/update-grub.in (GRUB_DISABLE_LINUX_UUID): Export variable.
* util/grub.d/10_linux.in: If GRUB_DEVICE_UUID is set, and
GRUB_DISABLE_LINUX_UUID isn't true, use the filesystem UUIDs as
the `root' parameter to Linux.
* commands/search.c (options): Rename --fs_uuid to --fs-uuid.
* util/update-grub_lib.in (prepare_grub_to_access_device): Replace
--fs_uuid with --fs-uuid.
* util/update-grub.in: Allow filesystem UUID probes to fail (since not
all filesystems support them).
* util/grub.d/00_header.in: Remove obsolete comment referencing
convert_system_path_to_grub_path().
* util/update-grub.in: Likewise.
* util/update-grub_lib.in (is_path_readable_by_grub): New function.

that this function is deprecated. Rely on is_path_readable_by_grub()
for the readability checks.

check rather than convert_system_path_to_grub_path().
* util/update-grub_lib.in (prepare_grub_to_access_device): New function.
* util/update-grub.in: Set `GRUB_FONT_PATH' to the system path, without
converting it first.
* util/grub.d/00_header.in: Use prepare_grub_to_access_device() to setup
grub.cfg for access to font file, and afterwards call it again to set
the root device.
* commands/search.c (options): Add --fs_uuid option.
(search_fs_uuid): New function.
(grub_cmd_search): Fix --set argument passing.
Use search_fs_uuid() when requested via --fs_uuid.

* util/grub.d/00_header.in: Set root using `search --fs_uuid' command

(make_device_name): Remove assumption of BIOS-like drive names.
* include/grub/script.h: Don't include grub_script.tab.h. It's
a generated file, which may only be included from the files with
DEPENDENCIES rules in the makefile. Don't use typedef YYSTYPE,
use union YYSTYPE, as the later allows forward declaration.
* normal/lexer.c: Don't use typedef YYSTYPE, use union YYSTYPE.
* fs/fshelp.c (grub_fshelp_map_block): New function.
(grub_fshelp_find_file): Use 64-bit type for pos and block address.

using grub_reiserfs_get_journal.
(grub_reiserfs_close): Release memory used by journal.
