From 1f66c45db3302386ca3bb3b5ed05248434237fc9 Mon Sep 17 00:00:00 2001 From: Vincenzo Frascino Date: Fri, 21 Jun 2019 10:52:48 +0100 Subject: [PATCH] mips: Add clock_gettime64 entry point With the release of Linux 5.1 has been added a new syscall, clock_gettime64, that provided a 64 bit time value for a specified clock_ID to make the kernel Y2038 safe on 32 bit architectures. Update the mips32 specific vDSO library accordingly with what it has been done for the kernel syscall exposing the clock_gettime64 entry point.
