void spu_setup_kernel_slbs	(	struct spu *	spu,
		struct spu_lscsa *	lscsa,
		void *	code,
		int	code_size
	)

Setup the SPU kernel SLBs, in preparation for a context save/restore. We need to map both the context save area, and the save/restore code.

Because the lscsa and code may cross segment boundaires, we check to see if mappings are required for the start and end of each range. We currently assume that the mappings are smaller that one segment - if not, something is seriously wrong.
