Subject: [PATCH v2 1/2] MIPS: Convert read_persistent_clock() to read_persistent_clock64()
Since struct timespec is not y2038 safe on 32bit machines, this patch
converts read_persistent_clock() to read_persistent_clock64() using
struct timespec64, as well as converting mktime() to mktime64().
Signed-off-by: Baolin Wang <baolin.wang@...aro.org>
