Subject[PATCH 1/3] perf/x86/intel/pt: Move pt structure to global header
Date
Intel PT structure (struct pt) is in a private header.
Move it (and sub structure) to a global header so that
it can be accessible from KVM code.

The definition of perf_output_handle structure included
in "linux/perf_event.h".
