From: Cyrill Gorcunov Date: Thu, 18 Mar 2010 21:12:56 +0000 (+0300) Subject: x86, perf: Fix few cosmetic dabs for P4 pmu (comments and constantify) X-Git-Tag: upstream/snapshot3+hdmi~14098^2~213 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9c8c6bad3137112d2c7bf3d215b736ee4215fa74;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git x86, perf: Fix few cosmetic dabs for P4 pmu (comments and constantify) - A few ESCR have escaped fixing at previous attempt. - p4_escr_map is read only, make it const. Nothing serious.
