What happened with Peter's comment about using flush_tlb_range for this? flush_tlb_mm() API should just stay unchanged AFAIKS.

Possibly passing in the rage for that guy is OK, which x86 can then implement as flush range. -- To unsubscribe from this list: send the line "unsubscribe linux-arch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
