[PATCH V3 1/2] hil_mlc: convert timeval to time64_t

From: WEN Pingbo
Date: Sat Oct 24 2015 - 00:01:27 EST


Since mlc->lcv_t is only interested in seconds,
directly using time64_t here

Signed-off-by: WEN Pingbo <pingbo.wen@xxxxxxxxxx>

Version 2:
Convert timeval to ktime_t
Version 3:
Convert it to time64_t, since it's a better choice
