High resolution timer support. Implemented for x86 CPUs using TSC.
Extracted generic grub_millisleep() so it's linked in only as needed.
This requires a Pentium compatible CPU; if the RDTSC instruction is
not supported, then it falls back on the generic grub_get_time_ms()
implementation that uses the machine's RTC.

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).
* disk/memdisk.c (memdisk_size): Don't initialize.

* kern/i386/pc/startup.S (grub_memdisk_image_size): Remove variable.
(codestart): Don't add grub_memdisk_image_size to %ecx in LZMA
decompression routine (grub_total_module_size already includes that
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.
* util/elf/grub-mkimage.c (options): Add "memdisk"|'m' option.

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.

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.

grub_console_gotoxy() to go back to beginning of the screen.

Add `-f' to `mv' to handle the different filesystem
semantics of Windows.

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.
* fs/xfs.c (grub_xfs_dir_header): Change field i8count back to
smallino, as it's more descriptive, and i8count can be confused with
the other field count.

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.
* util/i386/pc/grub-install.in: If `--debug' is specified,
pass `--verbose' to grub-setup.
Abort script if make_system_path_relative_to_its_root() fails.

start symbol in non pc platform.

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.
* aclocal.m4 (grub_PROG_OBJCOPY_ABSOLUTE): Replace -Wl,-N by
TARGET_IMG_LDFLAGS_AC.
(grub_CHECK_STACK_ARG_PROBE): New function.
* conf/i386-pc.rmk: Replace -Wl,-N by TARGET_IMG_LDFLAGS.

* configure.ac: Add check for linker script "conf/${target}-img-ld.c"
to set TARGET_IMG_LD* accordingly.
Add check for Cygwin to set TARGET_MOD_OBJCOPY accordingly.
Add call to grub_CHECK_STACK_ARG_PROBE.
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.
* util/grub.d/40_custom.in: New file. Example on how to add custom
entries to /etc/grub.d.
* conf/common.rmk (%, update-grub_SCRIPTS, CLEANFILES): Install
40_custom (implicitly, by merging all the grub.d rules).

[!GRUB_MACHINE_PCBIOS] (serial_hw_io_addr): Add COM2 and COM3.
(serial_hw_get_port): Check validity of the port number.
(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.
* 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.
* 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.
