Merge tag 'perf-core-for-mingo-20160718' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
User visible changes:
- Properly report when a function wildcard produces no matches in 'perf probe'
(Masami Hiramatsu)
- Balance opening and reading events in 'perf stat', which could cause
it to get stuck trying to close invalid file descriptors (Mark Rutland)
Infrastructure changes:
- Copy more headers from the kernel, this time for headers that
were just including the contents of its kernel counterparts, should
help resolving the problems with linux-next, where some uapi related
patches seem to be breaking tools/object/ build. (Arnaldo Carvalho de Melo)
Some more combing will be done, but at least it is possible to build
perf out of tree, via a detached tarball (make help | grep perf),
without including kernel files in its MANIFEST (Arnaldo Carvalho de Melo)
- Fix smatch found errors that were not causing problems, but are
mistakes nonetheless (Dan Carpenter)
- Fix string vs. byte array resolving in the python script code (Jiri Olsa)
