From 1d80415db64b54141ef02ae58bd2f273d0ac3c38 Mon Sep 17 00:00:00 2001 From: Chirantan Ekbote Date: Thu, 12 Jun 2014 00:18:48 +0900 Subject: [PATCH] clocksource: exynos_mct: Don't reset the counter during boot and resume Unfortunately on some exynos systems, resetting the mct counter also resets the architected timer counter. This can cause problems if the architected timer driver has already been initialized because the kernel will think that the counter has wrapped around, causing a big jump in printk timestamps and delaying any scheduled clock events until the counter reaches the value it had before it was reset. The kernel code makes no assumptions about the initial value of the mct counter so there is no reason from a software perspective to clear the counter before starting it. This also fixes the problems described in the previous paragraph.
