Pull perf tools fixes from Arnaldo Carvalho de Melo:

 - Don't group events when computing metrics that require more than the
   maximum number of simultaneously enabled events on AMD systems.

 - Fix multi CU handling in 'perf probe', add a 'perf test' entry to
   regress test it.

 - Make the 'perf test task_exit' stop generating samples by using the
   'dummy' event, all it is testing is if a PERF_RECORD_EXIT is
   generated at the end of a perf session. This makes this perf test to
   stop sometimes failing on some systems due to a full ring buffer.

 - Avoid SEGV if PMU lookup fails for legacy cache terms.

 - Fix libsubcmd SEGV/use-after-free when commands aren't excluded.

 - Fix OpenCSD (ARM64's CoreSight hardware tracing) library path
   resolution when specifying CSLIBS= in the make command line.

 - Fix broken feature check for libtracefs due to external lib changes,
   use the provided pkgconfig file instead future proof it.

 - Sync drm, fcntl, kvm, mount, prctl, socket, vhost, asound, arm64's
   cputype headers with the kernel sources, in some cases this made the
   tools become aware of new kernel APIs such as ioctls and the
   cachestat sysctl.
