Subject: [PATCH perf/core v5 00/15] perf-probe --cache and SDT support

Hi,

Here is the 5th version of the patchset for probe-cache and 
initial SDT support which are going to be perf-cache finally.

The previous version is here; https://lkml.org/lkml/2016/4/26/179

This version fixes a build bug on "make build-test", removed
accepted patches, and fold buildid-cache style change and backward
compatibility patches.
IOW, just a cleanup version :)

TODOs are here, but I think it should involve kernel-side change
to complete.
 - (perf record) Support SDT event recording directly
 - (perf record) Support @FILE/@...LDID suffix to record specific SDTs.
 - (perf record) Try to unregister SDT events after record.
 - (ftrace) Support multiple SDTs on single event.

Thank you,

---
