Subject: [PATCH v1 06/10] perf/x86/uncore: move uncore_event_to_box() and uncore_pmu_to_box()
Date: Mon, 3 Feb 2014 13:55:38 +0100 [thread overview]
Message-ID: <1391432142-18723-7-git-send-email-eranian@google.com> (raw)
In-Reply-To: <1391432142-18723-1-git-send-email-eranian@google.com>
Move a couple of functions around to avoid forward declarations
when we add code later on.
