It looks you may have broken paravirt (if even that case worked) because the iret is actually at the iret_label you removed (after the instruction is patched.) And most likely neither version worked with "noreplace-paravirt', because then the iret instruction is out-of-line and the INTERRUPT_RETURN jumps to it. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
