From: Steven Rostedt <[email protected]> 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.
