From c7405d85d7a354b8ba49e2db7c4b027e6cb997c1 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Thu, 31 Oct 2013 13:58:30 +0900 Subject: [PATCH] perf tools: Update cpumode for each cumulative entry The cpumode and level in struct addr_localtion was set for a sample and but updated as cumulative callchains were added. This led to have non-matching symbol and cpumode in the output. Update it accordingly based on the fact whether the map is a part of the kernel or not. This is a reverse of what thread__find_addr_map() does.
