Subject: [PATCH 05/12] tools headers uapi: Update tools's copy of linux/perf_event.h

From: Kan Liang <kan.liang@...ux.intel.com>

To get the changes in:

    ("perf/core: Add PERF_SAMPLE_WEIGHT_EXT")

This cures the following warning during perf's build:

        Warning: Kernel ABI header at
'tools/include/uapi/linux/perf_event.h' differs from latest version at
'include/uapi/linux/perf_event.h'
        diff -u tools/include/uapi/linux/perf_event.h
include/uapi/linux/perf_event.h
