Subject: [PATCH 34/37] s390: Remove unused cputime definitions
Date: Sun, 22 Jan 2017 19:20:10 +0100 [thread overview]
Message-ID: <1485109213-8561-35-git-send-email-fweisbec@gmail.com> (raw)
In-Reply-To: <1485109213-8561-1-git-send-email-fweisbec@gmail.com>
Since the core doesn't deal with cputime_t anymore, most of these APIs
have been left unused. Lets remove these.
