* Makefile.in (LIBLZO): New variable.

        * configure.ac: Check for LZO version 2.

        * util/i386/pc/grub-mkimage.c [HAVE_LZO_LZO1X_H]: Include
        lzo/lzo1x.h instead of lzo1x.h.

        * conf/i386-pc.rmk (grub_mkimage_LDFLAGS): Use $(LIBLZO) instead
        of -llzo.

        * util/i386/pc/grub-setup.c (main): Do not free PREFIX
        twice. Reported by Vladimir Serbinenko <phcoder@gmail.com>.

        * partmap/pc.c (pc_partition_map_probe): Restore P->DATA after
        copying the data from PARTITION to P.

* util/i386/pc/grub-install.in (grub_probefs): New variable.
        (modules): Likewise.
        (usage): Added descriptions for --modules and --grub-probefs.
        Handle --modules and --grub-probefs. Save the arguments in MODULES
        and GRUB_PROBEFS, respectively.
        Auto-detect a filesystem module against GRUBDIR. If the result is
        empty and modules are not specified explicitly, abort the
        installation. Add the result to MODULES.

        * DISTLIST: Removed boot/powerpc/ieee1275/ieee1275.c,
        disk/powerpc/ieee1275/ofdisk.c,
        include/grub/powerpc/ieee1275/init.h and
        term/powerpc/ieee1275/ofconsole.c.
        Added disk/ieee1275/ofdisk.c, kern/ieee1275/of.c and
        term/ieee1275/ofconsole.c.

        * include/grub/powerpc/ieee1275/console.h: Resurrected.

        * COPYING: Upgraded to the latest version. Only the address of the
        FSF office has changed.

All symbols prefixed with PUPA_ and pupa_ are renamed to GRUB_
	and grub_, respectively. Because the conversion is trivial and
	mechanical, I omit the details here. Please refer to the CVS
	if you need more information.

* include/pupa/i386/pc/linux.h: New file.
	* loader/i386/pc/linux.c: Likewise.

	* loader/i386/pc/chainloader.c (pupa_chainloader_boot_sector):
	Removed.
	(pupa_chainloader_unload): Return PUPA_ERR_NONE.
	(pupa_rescue_cmd_chainloader): Read the image to 0x7C00 instead
	of PUPA_CHAINLOADER_BOOT_SECTOR.

	(pupa_linux_prot_size): New variable.
	(pupa_linux_tmp_addr): Likewise.
	(pupa_linux_real_addr): Likewise.
	(pupa_linux_boot_zimage): New function.

	(pupa_upper_mem): Likewise.
	(add_mem_region): New function.
	(compact_mem_regions): Likewise.
	(pupa_machine_init): Set PUPA_LOWER_MEM and PUPA_UPPER_MEM to
	the size of the conventional memory and that of so-called upper
	memory (before the first memory hole).
	Instead of adding each found region to free memory, use
	add_mem_region and add them after removing overlaps.
	Also, add only 1/4 of the upper memory to free memory. The rest
	is used for loading OS images. Maybe this is ad hoc, but this
	makes it much easier to relocate OS images when booting.

	* kern/rescue.c (pupa_rescue_cmd_module): Removed.
	(pupa_enter_rescue_mode): Don't register initrd and module.

	* kern/mm.c: Include pupa/dl.h.

	* kern/loader.c (pupa_loader_load_module_func): Removed.
	(pupa_loader_load_module): Likewise.

	* kern/dl.c (pupa_dl_load): Use the suffix ``.mod'' instead of
	``.o''.

	* include/pupa/i386/pc/loader.h (pupa_linux_prot_size): Declared.
	(pupa_linux_tmp_addr): Likewise.
	(pupa_linux_real_addr): Likewise.

	* include/pupa/i386/pc/init.h (pupa_lower_mem): Declared.
	(pupa_upper_mem): Likewise.
	(pupa_gate_a20): Don't export, because turning off Gate A20 in a
	module is too dangerous.

	* include/pupa/loader.h (pupa_os_area_addr): Declared.
	(pupa_os_area_size): Likewise.
	(pupa_loader_set): Remove the first argument. Loader doesn't
	manage modules or initrd any longer.
	(pupa_loader_load_module): Removed.

	* conf/i386-pc.rmk (pkgdata_MODULES): Added linux.mod.
	(linux_mod_SOURCES): New variable.

* util/i386/pc/pupa-setup.c (setup): Define the internal
	function find_first_partition_start at the top level, because GCC
	3.0.x cannot compile internal functions in deeper scopes
	correctly.
	(find_root_device): Use lstat instead of stat.
	Don't follow symbolic links.
	Fix the path-constructing code.

	* util/i386/pc/biosdisk.c [__linux__] (BLKFLSBUF): New macro.
	(pupa_util_biosdisk_open) [__linux__]: Get the size of a device
	by a BLKGETSIZE ioctl first, because block devices don't fill
	the member st_mode of the structure stat on Linux.
	[__linux__] (linux_find_partition): Use a temporary buffer
	REAL_DEV for the working space. Copy it to DEV before returning.
	(open_device) [__linux__]: Call ioctl with BLKFLSBUF to make the
	buffer cache consistent.
	(get_os_disk) [__linux__]: Use the length 5 instead of 4 for
	strncmp. The previous value was merely wrong.
	(pupa_util_biosdisk_get_pupa_dev): Use stat instead of lstat.

	* fs/fat.c (pupa_fat_read_data): Shift 4 instead of 12 when the
	FAT size is 12. The previous value was merely wrong.

	* kern/main.c (pupa_main): Don't split the starting message from
	newlines.

	* kern/term.c (pupa_putchar): Put CR after LF instead of before
	LF, because BIOS goes crazy about character attributes in this
	case.

Use -mrtd and -mregparm=3 to reduce the generated code sizes.
	This means that any missing prototypes could be fatal. Also, you
	must take care when writing assembly code. See the comments at
	the beginning of startup.S, for more details.

	* kern/i386/pc/startup.S (pupa_halt): Modified for the new
	compilation mechanism.
	(pupa_chainloader_real_boot): Likewise.
	(pupa_biosdisk_rw_int13_extensions): Likewise.
	(pupa_biosdisk_rw_standard): Likewise.
	(pupa_biosdisk_check_int13_extensions): Likewise.
	(pupa_biosdisk_get_diskinfo_int13_extensions): Likewise.
	(pupa_biosdisk_get_diskinfo_standard): Likewise.
	(pupa_get_memsize): Likewise.
	(pupa_get_mmap_entry): Likewise.
	(pupa_console_putchar): Likewise.
	(pupa_console_setcursor): Likewise.
	(pupa_getrtsecs): Use pushl instead of push.

	* kern/i386/pc/init.c (pupa_machine_init): Use the scratch
	memory instead of the stack for a mmap entry, because some
	BIOSes may ignore the maximum size and overflow.

	* conf/i386-pc.rmk (COMMON_CFLAGS): Added -mrtd and -mregparm=3.

	* genmk.rb (PModule#rule): Compile automatically generated
	sources with module-specific CFLAGS as well as other sources.
