Subject: [PATCH 11/33] perf tools: Fix missing kernel map load
Date: Thu, 17 Jul 2014 13:12:13 -0300 [thread overview]
Message-ID: <1405613555-23380-12-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1405613555-23380-1-git-send-email-acme@kernel.org>
From: Adrian Hunter <adrian.hunter@intel.com>
thread__find_addr_map() falls back to trying the kernel maps if the
address is negative and is not found in userspace maps. As commented in
the code, the kernel maps must be "loaded" before use. This patch
ensures that happens under the fallback condition also.
