From: Jeremy Fitzhardinge <[email protected]> commit 9ecd4e1689208afe9b059a5ce1333acb2f42c4d2 upstream.
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.
