Revision ba48d40713ae5afe758dd5525a0f8740cce71d22 authored by Jon Medhurst on 07 April 2011, 12:25:19 UTC, committed by Nicolas Pitre on 29 April 2011, 03:40:56 UTC
The instructions space for 'Multiply and multiply-accumulate' instructions contains some undefined patterns. We need to reject probing of these because they may in future become defined and the kprobes code may then emulate them faultily. This has already happened with the new MLS instruction which this patch also adds correct decoding for as well as tightening up other decoding tests. (Before this patch the wrong emulation routine was being called for MLS though it still produced correct results.)
