To get the changes in:

  6cbc304f2f36 ("perf/x86/intel: Fix unwind errors from PEBS entries (mk-II)")

That do not imply any changes in the tooling side, the (ab)use of
sample_type is entirely done in kernel space, nothing for userspace to
witness here.

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'
