Subject: [PATCH RESEND 34/36] s390: Remove unused cputime definitions
Date: Tue, 31 Jan 2017 04:09:49 +0100 [thread overview]
Message-ID: <1485832191-26889-34-git-send-email-fweisbec@gmail.com> (raw)
In-Reply-To: <1485832191-26889-1-git-send-email-fweisbec@gmail.com>
In-Reply-To: <1485751603-15913-1-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.
