Subject[PATCH perf/core v8 00/16] perf-probe --cache and SDT support

Here is the 8th version of the patchset for probe-cache and
initial SDT support.

The previous version is here;

This version I droped the second patch in v7 because it may
involves unintended behavior change and we'd better discuss it
out of this series. I also added comments why we can't use
access(R_OK) for /proc/kcore.

Hemant, could you review and test this series so that we can
proceed to your patch depending on this?

Thank you,
