From cb850717b076d979058d52529e15f1736359d811 Mon Sep 17 00:00:00 2001 From: Xunlei Pang Date: Wed, 1 Apr 2015 20:34:26 -0700 Subject: ARM, clocksource/drivers: Provide read_boot_clock64() and read_persistent_clock64() and use them As part of addressing "y2038 problem" for in-kernel uses, this patch converts read_boot_clock() to read_boot_clock64() and read_persistent_clock() to read_persistent_clock64() using timespec64 by converting clock_access_fn to use timespec64.
