H A DMakefile258af474 Wed Sep 22 21:22:25 CDT 2010 Steven Rostedt <srostedt@redhat.com> 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.
