Subject: [PATCH 06/19] perf ui/hist: Consolidate hpp helpers
Date: Tue, 22 Jan 2013 18:09:34 +0900	[thread overview]
Message-ID: <1358845787-1350-7-git-send-email-namhyung@kernel.org> (raw)
In-Reply-To: <1358845787-1350-1-git-send-email-namhyung@kernel.org>

From: Namhyung Kim <namhyung.kim@lge.com>

Most of hpp helper functions do same jobs for different fields thus
consolidate them to appropriate functions/macros.
