don't spill beyond GRUB_KERNEL_MACHINE_RAW_SIZE.
* kern/i386/pc/lzo1x.S: Remove all .align directives in the
code, as they push parts of the code (error handlers) beyond
GRUB_KERNEL_MACHINE_RAW_SIZE. Speed is not as important in this
code as correctness and size.

(grub_biosdisk_get_diskinfo_int13_extensions): When converting
data block address to the real mode, keep offset minimal. This

Discard the second scan code that is always sent by Caps lock.
Only use `keyboard_map_shift' when it provides a non-zero value,
otherwise fallback to `keyboard_map'.

is still only the data handling part.

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.
