* 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.
