From 258af47479980d8238a04568b94a4e55aa1cb537 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Wed, 22 Sep 2010 22:22:25 -0400 Subject: [PATCH] tracing/x86: Don't use mcount in kvmclock.c The guest can use the paravirt clock in kvmclock.c which is used by sched_clock(), which in turn is used by the tracing mechanism for timestamps, which leads to infinite recursion. Disable mcount/tracing for kvmclock.o.
