From 50f16a8bf9d7a92c437ed1867d0f7e1dc6a9aca9 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Thu, 5 Mar 2015 22:10:19 +0100 Subject: perf: Remove type specific target pointers The only reason CQM had to use a hard-coded pmu type was so it could use cqm_target in hw_perf_event. Do away with the {tp,bp,cqm}_target pointers and provide a non type specific one. This allows us to do away with that silly pmu type as well.
