Subject: [PATCH v8 0/3] perf arm-spe: Add support for synthetic events

This patch set is to support synthetic events with enabling Arm SPE
decoder.  This patch set is based Xiaojun Tan (Hisilicon) and
James Clark (Arm)'s previous patches who have contributed much for
the related task.

This patch set has been checked with checkpatch.pl, though it leaves
several warnings, but these warnings are deliberately kept after
reviewing.  Some warnings ask to add maintainer (so far it's not
necessary), and some warnings complaint for patch 02 "perf auxtrace:
Add four itrace options" for the text format, since need to keep the
consistency with the same code format in the source code, this is why
this patch doesn't get rid of checkpatch warnings.

This patch set has been rebased on Perf tmp.perf/core branch with
latest commit 9300acc6fed8 ("perf build: Add a LIBPFM4=1 build test
entry").  The patches has been tested on Arm N1 machine (by James)
and on Hisilicon D06 platform (by Leo).

Changes from v7:
* Added James's tested-by tags;
* Rebased on Perf tmp.perf/core branch.

Tan Xiaojun (3):
  perf tools: Move arm-spe-pkt-decoder.h/c to the new dir
  perf auxtrace: Add four itrace options
  perf arm-spe: Support synthetic events
