Yes, as pointed out be several people, that would be better.

The swiotlb_init_with_tbl() didn't exist in earlier kernel versions and 
this simplification was missed when I forward ported the patch set.

By using this function, I think the entire patch set will be MIPS 
specific, making it unnecessary to touch the generic swiotlb code.

Thanks,
