[PATCH] x86/vmware: Do not trace vmware_sched_clock()
From: Steven Rostedt (VMware) <rostedt at goodmis.org>
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.

[PATCH 3/3] x86/vmware: Add paravirt sched clock
Set pv_time_ops.sched_clock to vmware_sched_clock(). It is simplified
version of native_sched_clock() without ring buffer of mult/shift/offset
triplets and preempt toggling.
Since VMware hypervisor provides constant tsc we can use constant
mult/shift/offset triplet calculated at boot time.
no-vmw-sched-clock kernel parameter is added to switch back to the
native_sched_clock() implementation.

You are not switching back. The parameter is used to disable the paravirt
sched clock.

[PATCH] x86/paravirt: Do not trace _paravirt_ident_*() functions
I just spent half a day bisecting function tracing because I tripped
over this again. I thought this was merged, but I guess it was missed
again.
Can someone please pull this in. And mark it for stable, it goes
probably as far back as 2.6.32.
Thanks!

[PATCH] x86/paravirt: Do not trace _paravirt_ident_*() functions
?ukasz Daniluk reported that on a RHEL kernel that his machine would lock up
after enabling function tracer. I asked him to bisect the functions within
available_filter_functions, which he did and it came down to three:
_paravirt_nop(), _paravirt_ident_32() and _paravirt_ident_64()
It was found that this is only an issue when noreplace-paravirt is added to
the kernel command line.
