for powerpc & i386-pc. This patch was more so started by Hollis
Blanchard getting multiboot 2 working for powerpc and I added to it
and cleaned it up.
One of the ideas with this patch is to keep everything under one
command for the user. So instead of having a "multiboot2" & "module2"
command, I created a proxy like mechanism so that you have only one
command for both multiboot 1 & 2 ... "multiboot". This is where
"loader/multiboot_loader.c" comes from. I could have integrated things
more but I figure the current approach will less likely break
anything.
So if your OS is multiboot 2 capable, the user would do the following
to load it up from a grub prompt:
grub> multiboot <location of kernel> <kernel args>
grub> module <some image> <multiboot tag> <image arguments>
grub> module <isome mage> <multiboot tag> <image arguments>
grub .....
The other thing that this patch does is it begins to make the
multiboot 1 code a bit more architecture agnostic so IF someone wanted
to implement it on another architecture they can.
A bit of file moving around and definition renaming is also apart of
this patch. I have also taken the time to make sure that it does not
break multiboot 1 loading on i386-pc. But mulitboot 2 may still need a
little more testing and work for i386-pc. Powerpc multiboot 2 has been
heavily tested and does work.

rmmod and lsmod.
* kern/mm.c (pupa_memalign): If failed even after invalidating
disk caches, unload unneeded modules and retry.
* kern/misc.c (pupa_memmove): New function.
(pupa_memcpy): Removed.
(pupa_strcpy): New function.
(pupa_itoa): Made static.

(pupa_dl_set_prefix): ... this.
(pupa_dl_get_prefix): New function.
* include/pupa/i386/pc/kernel.h: Include pupa/types.h.
(PUPA_KERNEL_MACHINE_INSTALL_DOS_PART): New macro.
(PUPA_KERNEL_MACHINE_INSTALL_BSD_PART): Likewise.
(PUPA_KERNEL_MACHINE_PREFIX): Likewise.
(pupa_install_dos_part): Declared.

(pupa_prefix): Likewise.
(pupa_boot_drive): Likewise.
* include/pupa/types.h: Fix a typo.
* include/pupa/misc.h (pupa_memcpy): New macro. Just an alias to
pupa_memmove.
(pupa_memmove): Declared.
(pupa_strcpy): Likewise.
* include/pupa/dl.h (PUPA_MOD_INIT): Change the prototype. Now
pupa_mod_init takes one argument, its own module.
(pupa_dl_unload_unneeded): Declared.
(pupa_dl_unload_all): Likewise.
(pupa_dl_ref): Likewise.
(pupa_dl_unref): Likewise.
(pupa_dl_iterate): Likewise.

* fs/fat.c [!PUPA_UTIL] (my_mod): New variable.
(pupa_fat_dir) [!PUPA_UTIL]: Prevent the fat module from being
unloaded.
(pupa_fat_open) [!PUPA_UTIL]: Refer itself if succeeded.
(pupa_fat_close) [!PUPA_UTIL]: Unrefer itself.
* configure.ac (tmp_CFLAGS): Added -Wshadow, -Wpointer-arith,
-Wmissing-prototypes, -Wundef and -Wstrict-prototypes.
* 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_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.
