From d26b8655f088ac6e972fd8f016b8dfa7cc1b9e5a Mon Sep 17 00:00:00 2001 From: Alexander Yarygin Date: Thu, 30 Jan 2014 22:13:40 +0400 Subject: [PATCH] KVM: s390: Use intercept_insn decoder in trace event The current trace definition doesn't work very well with the perf tool. Perf shows a "insn_to_mnemonic not found" message. Let's handle the decoding completely in a parseable format.
