as opposed to after.

	* grub-core/Makefile.core.def (kernel): Increase linking address.
	(none_decompress): Likewise.
	(xz_decompress): Likewise.
	* grub-core/boot/mips/startup_raw.S: Use prewritten uncompression
	address.
	* grub-core/kern/mips/arc/init.c (grub_machine_init): Handle memory
	layout change.
	(grub_arch_modules_addr): New function.
	* grub-core/kern/mips/init.c (grub_arch_modules_addr): Moved from here...

	here.
	* grub-core/kern/mips/startup.S (total_size): Rename to ...
	(grub_total_modules_size): ... this. Make global.
	[GRUB_MACHINE_ARC]: Don't attempt to move modules out of the bss.
	* include/grub/offsets.h (GRUB_KERNEL_MIPS_LOONGSON_UNCOMPRESSED_ADDR):
	New definition.
