I think until we have the whole SEV situation sorted out, it's best to leave it as-is. Leaving the dsb in there shouldn't cause a problem for a v6+v6k+v7 kernel, it just means we're wasting a few cycles stalling the instruction pipeline while the dsb completes, which we don't really need to do on v6. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
