The facilities for identifying the PMU to the guest are very lacking, so it's hard to make this fail gracefully.

This only works on Intel hosts for now. -- error compiling committee.c: too many arguments to function -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
