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

2003-01-18 Yoshinori K. Okuji <okuji@enbug.org>
* kern/rescue.c (pupa_rescue_cmd_rmmod): Call pupa_dl_unload, if
possible.
* kern/dl.c (pupa_dl_ref): Refer dependending modules
recursively.
(pupa_dl_unref): Unrefer depending modules recursively.
Don't call pupa_dl_unload implicitly, because PUPA can crash if
a module is unloaded before one depending on that module is
unloaded.
(pupa_dl_unload): Unload depending modules explicitly,
if possible.
* 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_tmp_addr): 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''.

(pupa_linux_tmp_addr): Likewise.
(pupa_linux_real_addr): Likewise.
(pupa_linux_boot_zimage): Likewise.
(pupa_linux_boot_bzimage): 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.
(linux_mod_CFLAGS): Likewise.
* util/i386/pc/pupa-setup.c (setup): Convert the endianness of
the length of a blocklist correctly.
* util/i386/pc/biosdisk.c (pupa_util_biosdisk_open) [__linux__]:
Use ioctl only if the OS file is a block device.
(pupa_util_biosdisk_open): Don't use ST.ST_BLOCKS, because it is
not very useful for normal files.
* kern/main.c (pupa_set_root_dev): New function.
(pupa_load_normal_mode): Likewise.
(pupa_main): Call those above.
* include/pupa/types.h (pupa_swap_bytes16): Cast the result to
pupa_uint16_t.
* include/pupa/kernel.h (pupa_enter_normal_mode): Removed.
* 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.
