Subject: [PATCH v2 0/2] Fix check for trace_percpu_buffer validity

The first patch fixes how we check for validity of trace_percpu_buffer, 
fixing a kernel oops seen on ppc64le with the new osnoise tracer. The 
second patch is new in v2 and carries the change to tag the pointer as a 
percpu pointer.
