of modules instead of assuming which platform provides what.
* util/update-grub.in: Likewise.
* kern/i386/pc/init.c (make_install_device): Check for `grub_prefix'
instead of `grub_install_dos_part' to determine whether a drive needs
to be prepended to prefix (`grub_install_dos_part' is not reliable,
because it can be overriden when loading GRUB via Multiboot).

support multiple module types.
(grub_module_iterate): New function.

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.

(backward_relocator): New variables. Used to allocate and relocate
the payload, respectively.
(grub_multiboot_load_elf32): Load into heap instead of requested
address, install the appropiate relocator code in each bound of
the payload, and set the entry point such that
grub_multiboot_real_boot() will jump to one of them.
* kern/i386/loader.S (grub_multiboot_payload_size)
(grub_multiboot_payload_orig, grub_multiboot_payload_dest)
(grub_multiboot_payload_entry_offset): New variables.

(grub_multiboot_payload_entry_offset): Export.

ELF segments, use a macro for arbitrarily accessing any of them instead
of preparing a pointer that allows access to one at a time.

* include/grub/i386/pc/kernel.h (GRUB_KERNEL_MACHINE_DATA_END):
Increase from 0x50 to 0x60.
* util/i386/pc/grub-install.in: Detect cross-disk installs, and
use UUIDs to identify the root drive for them. If that's not
possible, abort.
* util/i386/pc/grub-setup.c (setup): Do not special-case, or even
check, for cross-disk installs.
* kern/ieee1275/init.c (grub_machine_set_prefix): If `grub_prefix'
is non-empty, use it to set the `prefix' environment variable instead
of the usual approach.
* kern/i386/linuxbios/init.c (make_install_device): Remove function.
(grub_machine_set_prefix): Use `grub_prefix' to set the `prefix'
environment variable instead of dummy make_install_device().

* kern/i386/linuxbios/startup.S: Likewise.

New macro. Defines offset of `grub_prefix' within startup.S (relative
to `start').

section within startup.S (relative to `start').
* include/grub/i386/coreboot/kernel.h: Likewise.

the partmap header.
(apple_partition_map_iterate): Check the header magic as well as the
partition magic (which was already being checked).

with the same number are found, just use issue a warning with
grub_dprintf(), as this error has been reported to be non-fatal.
* util/getroot.c (find_root_device): Skip devices that match
/dev/dm-[0-9]. This lets the real device be found for any type of
abstraction (LVM, EVMS, RAID..).
(grub_guess_root_device): Do not traverse /dev/mapper (for LVM)
and /dev/evms (for EVMS) before traversing /dev. If a /dev/dm-[0-9]
device is found first, find_root_device() will now skip it.
* Makefile.in (UNICODE_ARROWS, UNICODE_LINES): New variables (they
define the codes for arrows and lines used for the menu).
(ascii.pff): Generate fonts for $(UNICODE_ARROWS) and $(UNICODE_LINES)
as well.
* util/update-grub_lib.in (font_path): Prefer ascii.pff over complete
fonts, because the latter are too slow.

entries to /etc/grub.d.
* conf/common.rmk (%, update-grub_SCRIPTS, CLEANFILES): Install
40_custom (implicitly, by merging all the grub.d rules).
This fixes a performance issue when pc & gpt partmap iterators
didn't abort iteration even after our hook found what it was
looking for (often causing expensive probes of non-existant drives).
Some callers relied on previous buggy behaviour, since they would
rise an error when their own hooks caused early abortion of its
iteration.
* kern/device.c (grub_device_open): Improve error message.
* disk/lvm.c (grub_lvm_open): Likewise.
* disk/raid.c (grub_raid_open): Likewise.
* partmap/pc.c (pc_partition_map_iterate): Abort parent iteration
when hook requests it, independently of grub_errno.
(pc_partition_map_probe): Do not fail when find_func() caused
early abortion of pc_partition_map_iterate().
* partmap/gpt.c (gpt_partition_map_iterate): Abort parent iteration
when hook requests it, independently of grub_errno.
(gpt_partition_map_probe): Do not fail when find_func() caused
early abortion of gpt_partition_map_iterate().
* kern/partition.c (grub_partition_iterate): Abort parent iteration
when hook requests it, independently of grub_errno. Do not fail when
part_map_iterate_hook() caused early abortion of p->iterate().
* util/biosdisk.c (grub_util_biosdisk_get_grub_dev): Do not fail
when grub_partition_iterate() returned with non-zero.
* fs/xfs.c (GRUB_XFS_FSB_TO_BLOCK): New macro. Maps filesystem
block to disk block.
(grub_xfs_read_block): Use GRUB_XFS_FSB_TO_BLOCK() on result.
Patch from Niels B\303\266hm <bitbucket@arcor.de>
* util/update-grub_lib.in (font_path): Search for fonts in
/boot/grub first, which is more likely to be readable (we aren't
deciding where fonts live, just looking for them).
* util/grub.d/10_linux.in: Avoid passing UUIDs to Linux when either
"/dev/disk/by-uuid/${GRUB_DEVICE_UUID}" does not exist, or when a
Linux image includes no initrd.
* util/grub.d/00_header.in: Move last prepare_grub_to_access_device()
call from here ...
* util/grub.d/10_hurd.in: ... to here ...
* util/grub.d/10_linux.in: ... and here.
* commands/search.c (search_label, search_fs_uuid, search_file): Print
search result when not saving to variable, not the other way around.
When saving to variable, abort iteration as soon as a match is found.
* util/update-grub_lib.in (prepare_grub_to_access_device): Remove
check for partition that provides /boot/grub. Its logic is flawed,
as it prevents prepare_grub_to_access_device() from being called
multiple times.
* util/update-grub_lib.in (prepare_grub_to_access_device): Issue
"insmod" command directly when abstraction modules are needed,
instead of reliing on GRUB_PRELOAD_MODULES (which had no effect
since it had already been processed).
* util/i386/pc/grub-install.in: If the drive is LVM or RAID, prepend
it in prefix.
* util/i386/pc/grub-setup.c (main): Don't handle prefix at all. Set
`must_embed' to 1 when root_dev is a RAID device. When dest_dev is
a RAID device, run setup() for all members independently on whether
LVM abstraction is being used.
(setup): Don't handle prefix at all; let grub-mkimage take care of it.
If grub-mkimage has set `*install_dos_part == -2', don't override this
value.
Perform *install_dos_part adjustments independently on whether
we're embedding or not.
Clarify error message when image is too big for embedding.
Remove duplicate *install_dos_part stanza.
* term/ieee1275/ofconsole.c (fgcolor, bgcolor): Remove variables.
(grub_ofconsole_normal_color, grub_ofconsole_highlight_color): New
variables.
(grub_ofconsole_setcolor, grub_ofconsole_getcolor): Load/store
values in grub_ofconsole_normal_color and
grub_ofconsole_highlight_color (they're not directly related to
background and foreground).
(grub_ofconsole_setcolorstate): Extract background and foreground
from grub_ofconsole_normal_color and grub_ofconsole_highlight_color.
* util/update-grub_lib.in (prepare_grub_to_access_device): Use
/boot/grub for the check in last commit, not /boot (they could be
different partitions).
* util/update-grub_lib.in (prepare_grub_to_access_device): If we were
asked to setup access for the same partition that provides /boot,
don't bother using UUIDs since our root already has the value we
want.
* util/i386/pc/grub-mkimage.c (generate_image): If we included a drive
in our prefix, set install_{dos,bsd}_part = -2 to indicate this can be
skipped later.
(main): If a memdisk was requested, add "(memdisk)" drive explicitly to
the beginning of the prefix.
* kern/i386/pc/init.c (make_install_device): Remove memdisk check.
It is assumed that if we have a memdisk, grub-mkimage has set
grub_prefix to include the "(memdisk)" drive in it.
* term/i386/pc/console.c [GRUB_MACHINE_LINUXBIOS] (grub_console_init):
Initialize keyboard controller after registering the terminal, so that
grub_printf() can be called from grub_keyboard_controller_init().
* fs/sfs.c (grub_sfs_read_extent): Fix the count of nodes in
extent-btree which is written as big endian on disk.

using "cursor-on" and "cursor-off" commands (understood at least by
the Open Firmware flavour on OLPC).
* 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.

* 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).
