Subject: [PATCH v2 11/11] xtensa: remove CCOUNT_PER_JIFFY
Date: Fri, 30 Aug 2013 19:35:03 +0400 [thread overview]
Message-ID: <1377876903-27860-12-git-send-email-jcmvbkbc@gmail.com> (raw)
In-Reply-To: <1377876903-27860-1-git-send-email-jcmvbkbc@gmail.com>
From: Baruch Siach <baruch@tkos.co.il>
Use ccount_freq directly to make the code a little more readable.
