From 5e06b6492e53ab2a4e467763a9ee9f70b032c301 Mon Sep 17 00:00:00 2001 From: Russell King Date: Wed, 15 Dec 2010 19:19:25 +0000 Subject: ARM: ensure all sched_clock() implementations are notrace marked ftrace requires sched_clock() to be notrace. Ensure that all implementations are so marked. Also make sure that they include linux/sched.h Also ensure OMAP clocksource read functions are marked notrace as they're used for sched_clock() too.
