From 5b7ba82a75915e739709d0ace4bb559cb280db09 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Wed, 7 Aug 2013 14:38:46 +0300 Subject: perf symbols: Load kernel maps before using In order to use kernel maps to read object code, those maps must be adjusted to map to the dso file offset. Because lazy-initialization is used, that is not done until symbols are loaded. However the maps are first used by thread__find_addr_map() before symbols are loaded. So this patch changes thread__find_addr() to "load" kernel maps before using them.
