Cover letter [PATCH perf/core v13 00/15] perf-probe --cache and SDT support

Hi,

Here is the 13th version of the patchset for probe-cache and initial SDT support.

Here is the previous v12: https://lkml.org/lkml/2016/6/24/147

In this version, I've removed the patch for perf-list to show SDT events, since at this point we don't support SDT from perf record. I also change perf-probe --cache --list to show cached events on only valid (existing) binaries.

Thank you,
