Subject: [PATCH -tip] x86, perf: A few cosmetic dabs for p4 pmu (comments and constantify)
Date: Fri, 19 Mar 2010 00:12:56 +0300 [thread overview]
Message-ID: <20100318211256.GH5062@lenovo> (raw)
- A few ESCR have escaped fixing at previous attempt.
- p4_escr_map is read only, make it const.
Nothing serious.
