Subject: x86/cpu/vmware: Do not trace vmware_sched_clock()

From: Steven Rostedt (VMware) <[email protected]>

commit 15035388439f892017d38b05214d3cda6578af64 upstream.

When running function tracing on a Linux guest running on VMware Workstation, the guest would crash. This is due to tracing of the sched_clock internal call of the VMware vmware_sched_clock(), which causes an infinite recursion within the tracing code (clock calls must not be traced).

Make vmware_sched_clock() not traced by ftrace.
