Subject: [RFC][PATCH] amdkfd: Convert timestamping to use 64bit time accessors
Date: Thu, 12 Mar 2015 10:23:40 -0700 [thread overview]
Message-ID: <1426181020-2344-1-git-send-email-john.stultz@linaro.org> (raw)
Convert the timestamping in the amdkfd driver to use
a timespec64 and 64bit time accessors.
