(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

the payload, respectively.
(grub_multiboot_load_elf32): Load into heap instead of requested
address, install the appropiate relocator code in each bound of

use UUIDs to identify the root drive for them. If that's not
possible, abort.

the partmap header.
(apple_partition_map_iterate): Check the header magic as well as the
partition magic (which was already being checked).
* disk/raid.c (grub_raid_scan_device): Do not abort when two disks
with the same number are found, just use issue a warning with
grub_dprintf(), as this error has been reported to be non-fatal.

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]

The following patches are from Christian Franke.
* include/grub/dl.h: Remove .previous, gas supports this only
for ELF format.
* include/grub/symbol.h [__CYGWIN__] (#define FUNCTION/VARIABLE):
Remove .type, gas supports this only for ELF format.
* kern/dl.c (grub_dl_resolve_dependencies): Add check for trailing
nullbytes in symbol table. This fixes an infinite loop if table is
zero filled.
* Makefile.in: Add autoconf replacements TARGET_IMG_LDSCRIPT,
TARGET_IMG_LDFLAGS and EXEEXT.

to set TARGET_IMG_LD* accordingly.
Add check for Cygwin to set TARGET_MOD_OBJCOPY accordingly.

Use TARGET_IMG_LDFLAGS to check start, bss_start, end symbols.
* genkernsyms.sh.in: Handle HAVE_ASM_USCORE case.
* genmk.rb: Add EXEEXT to CLEANFILES.
* 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.
* kern/dl.c: Go back to using GRUB_CPU_SIZEOF_VOID_P. We cannot
load foreign architecture modules correctly anyway. Keep
support for loading host architecture modules, whether we
compile them or not.
* aclocal.m4 (grub_PROG_TARGET_CC): New macro. Check if the
target compiler is functional.
* configure.ac: Call grub_PROG_TARGET_CC once all target flags
are set up.
* configure.ac: Default to efi platform for x86_64-apple. Allow
powerpc64 CPU, default to ieee1275 platform for it. Split CPU
adjustments from the rest, only do them if target is not
explicitly given. Merge other adjustments with the final sanity
check. Remove an extraneous check for supported CPU. Be
specific which CPU and which platform is not supported.
* util/i386/efi/grub-mkimage.c (get_target_address): Return a
pointer, not an integer. This fixes a warning and prevents
precision loss on 64-bit systems.
(relocate_addresses): Remove unneeded cast.

entries to /etc/grub.d.
* conf/common.rmk (%, update-grub_SCRIPTS, CLEANFILES): Install

(grub_cmd_serial): Check return value of serial_hw_get_port().
* boot/i386/pc/diskboot.S (notification_string): Replace
"Loading kernel" with just "loading". This is shorter, less
confusing and saves a few bytes for possible future changes.
* kern/i386/linuxbios/init.c (grub_machine_init): Cast addr to
grub_addr_t before casting it to the void pointer to fix a
warning. Non-addressable regions are discarded earlier.
(grub_arch_modules_addr): Cast _end to grub_addr_t.
* kern/i386/linuxbios/table.c: Include grub/misc.h.
(check_signature): Don't shadow table_header.
(grub_linuxbios_table_iterate): Cast numeric constants to
grub_linuxbios_table_header_t.
* include/grub/i386/linuxbios/init.h: Add noreturn attribute to
grub_stop().
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.

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.
* disk/ata.c (grub_ata_pio_write): Check status before writing,
like we do in grub_ata_pio_read().
(grub_ata_readwrite): Always write individual sectors. Fix the
sector count for the remainder.
(grub_ata_write): Enable writing to ATA devices. Correctly
report error for ATAPI devices.
* disk/ata.c (grub_ata_readwrite): Don't increment sector number
for every read sector, we already increment it for the whole
batch. This fixes reading more than 256 sectors at once.
* Makefile.in (MODULE_LDFLAGS): New variable.
* aclocal.m4 (grub_PROG_LD_BUILD_ID_NONE): New macro. Check if
the linker accepts --build-id=none.
* configure.ac: Call grub_PROG_LD_BUILD_ID_NONE. Substitute
MODULE_LDFLAGS.
* genmk.rb: Use MODULE_LDFLAGS when linking modules.
* fs/xfs.c (struct grub_xfs_dir_header): Use names similar to
those in Linux XFS code. Provide a way to access 64-bit parent
inode.

the end of struct grub_xfs_dir_header.
* include/grub/ieee1275.h (grub_ieee1275_flag): New constant
GRUB_IEEE1275_FLAG_CANNOT_INTERPRET, GRUB_IEEE1275_FLAG_FORCE_CLAIM
and GRUB_IEEE1275_FLAG_NO_ANSI.
* kern/ieee1275/cmain.c (grub_ieee1275_find_options): Set flag
GRUB_IEEE1275_FLAG_CANNOT_INTERPRET, GRUB_IEEE1275_FLAG_FORCE_CLAIM
and GRUB_IEEE1275_FLAG_NO_ANSI for Open Hackware.
* kern/ieee1275/ieee1275.c (grub_ieee1275_interpret): Return
immediately if GRUB_IEEE1275_FLAG_CANNOT_INTERPRET is set.
* kern/ieee1275/init.c (grub_claim_heap): Claim memory directly if
GRUB_IEEE1275_FLAG_FORCE_CLAIM is set.
* term/ieee1275/ofconsole.c (grub_ofconsole_writeesc): Don't output
esc sequence on non ANSI terminal.
(grub_ofconsole_gotoxy): Emulate backspace key on non ANSI terminal.
* util/elf/grub-mkimage.c (add_segments): Move ELF header to the
beginning of file.
* disk/raid.c: Cast grub_dprintf() arguments to unsigned long
long if the format specifier expects it.

* partmap/pc.c (pc_partition_map_iterate): Likewise.
* fs/ntfs.c (grub_ntfs_uuid): Cast data->uuid to unsigned long
long to fix a warning.
* fs/reiserfs.c (grub_reiserfs_read): Change casts in
grub_dprintf() arguments to fix warnings.
* util/i386/pc/grub-setup.c (setup): Write install_dos_part and
install_bsd_part immediately before core.img is embedded or
modified on disk. This fixes core.img verification if core.img
cannot be embedded.
* 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).
* conf/i386-efi.rmk: Recompile grub-mkimage.c if Makefile has
changed. This is needed in case GRUB_LIBDIR changes.
* conf/i386-ieee1275.rmk: Likewise.
* conf/i386-linuxbios.rmk: Likewise.
* conf/i386-pc.rmk: Likewise.
* conf/powerpc-ieee1275.rmk: Likewise.
* conf/powerpc-ieee1275.rmk (kernel_elf_SOURCES): Rename
kernel_elf_symlist.c to symlist.c for consistency with other
architectures. Update all users.
* conf/sparc64-ieee1275.rmk (kernel_elf_SOURCES): Likewise.
* 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.
* commands/ls.c (grub_ls_list_files): Use integer calculations
for human readable format, avoid floating point use.
* kern/misc.c (grub_ftoa): Remove.
(grub_vsprintf): Remove floating point support.
* 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.
Reported by Alain Greppin <al@chilibi.org>.
* 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().

* 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.
(fs_module, partmap_module, devabstraction_module): Pass
`--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'.

(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.
