From 9ecd4e1689208afe9b059a5ce1333acb2f42c4d2 Mon Sep 17 00:00:00 2001 From: Jeremy Fitzhardinge Date: Wed, 22 Sep 2010 17:07:27 -0700 Subject: tracing/x86: Don't use mcount in pvclock.c When using a paravirt clock, pvclock.c can be used by sched_clock(), which in turn is used by the tracing mechanism for timestamps, which leads to infinite recursion. Disable mcount/tracing for pvclock.o.
