Frederic Weisbecker 2c2d7329d8 tracing/ftrace: use preempt_enable_no_resched_notrace in ring_buffer_time_stamp() ...

Impact: prevent a trace recursion

After some tests with function graph tracer under x86-32, I saw some recursions
caused by ring_buffer_time_stamp() that calls preempt_enable_no_notrace() which
calls preempt_schedule() which is traced itself.

This patch re-enables preemption without rescheduling.
