Subject: [PATCH v6 01/26] tools headers uapi: Update tools's copy of linux/perf_event.h

To get the changes in:

Liang Kan's patch
[PATCH V6 21/25] perf: Extend PERF_TYPE_HARDWARE and PERF_TYPE_HW_CACHE

Kan's patch is upstreamed yet but perf/core branch doesn't have it
at this moment. But next perf tool patches need this interface for
hybrid support.

This patch can be removed after Kan's patch is merged in perf/core
branch.
