Merge tag 'perf-fdarray-for-mingo' of git://git./linux/kernel/git/acme/linux into perf/core

Pull perf tooling updates from Arnaldo Carvalho de Melo.

Infrastructure changes:

  * We were not handling POLLHUP notifications for event file descriptors.

    Fix it by filtering entries in the events file descriptor array after
    poll() returns, refcounting mmaps so that when the last fd pointing to
    a perf mmap goes away we do the unmap. (Arnaldo Carvalho de Melo)

User visible changes:

  * Now 'record' and 'trace' properly exit when a target thread exits.
    (Arnaldo Carvalho de Melo)
