Subject: [PATCH v4 0/5] perf cs-etm: Fix pid tracing with VHE

This patch set is to follow up the patch series "coresight: etm-perf:
Fix pid tracing with VHE" [1].

Since the kernel and documentation patches have been picked up by
Mathieu Poirier and will go through the char-misc-next branch [2] to the
mainline kernel; the rest patches are for the perf tool, so combine
these patches into this patch set.

The patch set can be cleanly applied on perf/core branch with:

  commit 6db59d357e8e ("perf arm64/s390: Fix printf conversion specifier for IP addresses")

And this patch set has been verified on Arm Juno-r2 board.

Changes from v3:
* Added Reviewed-by tags (Mathieu/Mike/Suzuki);
* Changed to use the existed macros for option bits in patch 02/05
  (Mathieu).
