variable declaration.
(grub_os_area_size): Likewise.
* kern/i386/ieee1275/init.c (grub_os_area_addr, grub_os_area_size)
(grub_lower_mem, grub_upper_mem): New variables.
(grub_stop_floppy): New function (just to make
grub_multiboot2_real_boot() happy).
* kern/i386/ieee1275/startup.S: Include `<grub/machine/memory.h>',
`<grub/cpu/linux.h>', `<multiboot.h>' and `<multiboot2.h>'.
(grub_stop): New function.
Include `"../realmode.S"' and `"../loader.S"'.
