Subject: [PATCH v3 1/2] MIPS: Convert read_persistent_clock() to read_persistent_clock64()
Date: Mon,  7 May 2018 17:28:27 +0800	[thread overview]
Message-ID: <c26982955db16b8f790e7f5f2a5b63e42bc78192.1525682212.git.baolin.wang@linaro.org> (raw)

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@linaro.org>
