Subject[030/103] tracing/x86: Dont use mcount in kvmclock.c
2.6.35-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Steven Rostedt <srostedt@redhat.com>

commit 258af47479980d8238a04568b94a4e55aa1cb537 upstream.

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.
