From 91bc9aaf746ae41016bd6b61a48133e162542574 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 21 Aug 2018 21:55:49 -0700 Subject: [PATCH] kernel/crash_core.c: print timestamp using time64_t The get_seconds() call returns a 32-bit timestamp on some architectures, and will overflow in the future. The newer ktime_get_real_seconds() always returns a 64-bit timestamp that does not suffer from this problem.
