Subject: [PATCH 1/3] powerpc: perf_event: Cleanup copy_page output by hiding setup symbol
Date: Sun, 18 Oct 2009 22:23:28 +1100 [thread overview]
Message-ID: <20091018112328.GN4808@kryten> (raw)
A lot of hits in "setup" doesn't make much sense, so hide this symbol and
allow all the hits to end up in copy_4k_page.
