I wasn't suggesting we shouldn't have both interfaces, merely questioning why adding what to me seems like an unnecessary performance hit for the classic case of the call.I don't mind how many interfaces there are, so long as there only needs to be one place to hook to plug in the Xen version of smp_call_function_whatever. Perhaps the answer is to just hook the IPI mechanism itself rather than the whole of smp_call_function_mask...
Well we're obviously going to have at least two interfaces given that we have the traditional Linux one and Xen seems to require something different :-)

Nope, do you have a pointer? Cheers, Jes -- To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
