Subject: [PATCH v2 00/11] perf events patches for improved ARM64 support

This patchset adds support for some perf events features,
targeted at ARM64, implemented in a generic fashion.

The two main features are as follows:
- support for arch/vendor/platform pmu events directory structure
   - to support this, topic subdirectory support needs to be dropped
- support for parsing standard architecture pmu events

On the back of these, the Cavium ThunderX2, ARM Cortex-A53,
and HiSilicon hip08 JSONs are relocated/added/updated.

In addition, there is a patch to drop mutli-mapfile.csv support and
also a bugfix in jevents.c for an error code value.

Differences to v1:
- Address coding issues from Jiri Olsa in adding arch std event
   support (https://lkml.org/lkml/2018/2/6/501)
- add patch to drop topic subdirectory support
- add patch for bug fix in json_events() 
- add review tags from Jiri Olsa

Differences to RFC:
- reworked patch for arch standard events
	- added arch standard event keyword support
	- use some macros to make the code more condense
	- use <linux/list_head.h>
- standardised some function names
- updated README
- for patch to support vendor subdir, add check for
  unknown dirent type
 -add patch to drop mutliple mapfile.csv support
 - dealt with new cortex a53 JSONs


John Garry (11):
  perf vendor events: drop incomplete multiple mapfile support
  perf vendor events: fix error code in json_events()
  perf vendor events: drop support for unused topic directories
  perf vendor events: add support for pmu events vendor subdirectory
  perf vendor events arm64: Relocate ThunderX2 JSON to cavium
    subdirectory
  perf vendor events arm64: Relocate Cortex A53 JSONs to arm
    subdirectory
  perf vendor events: add support for arch standard events
  perf vendor events arm64: add armv8-recommended.json
  perf vendor events arm64: fixup ThunderX2 to use recommended events
  perf vendor events arm64: fixup A53 to use recommended events
  perf vendor events arm64: add HiSilicon hip08 JSON file
