Subject: [RFC PATCH 0/5] 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
- support for parsing architecture recommended pmu events

On the back of these, the Cavium ThunderX2 and HiSilicon hip08
JSONs are relocated/added.

TODO: 
	- Documentation needs to be updated for recommended
	events format in the JSON
	- tidy up patches a bit

John Garry (5):
  perf jevents: add support for pmu events vendor subdirectory
  perf jevents: add support for arch recommended events
  perf vendor events arm64: add armv8 recommended events JSON
  perf vendor events arm64: relocate thunderx2 JSON
  perf vendor events arm64: add HiSilicon hip08 JSON
