From: Will Deacon Date: Fri, 3 Jun 2011 16:38:49 +0000 (+0100) Subject: ARM: perf: remove confusing comment from v7 perf events backend X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7b35fa47eecd0c746924a6d6c2a897d2cec778ba;p=linux-beck.git ARM: perf: remove confusing comment from v7 perf events backend The comment about measuring TLB misses and refills in the ARMv7 perf backend makes little sense and refers loosely to raw counters that should be used instead. This patch removes the comments to avoid any confusion.
