Merge tag 'perf-core-for-mingo-4.12-20170327' 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:

New features:

 - Handle inline functions in callchains (Jin Yao)

 - Enable sorting by srcline as key (Milian Wolff)

Fixes:

 - Fix no_size logic in addr_filter__resolve_kernel_syms() in the
   auxtrace code (Adrian Hunter)

 - Fix some thread refcount leaks in 'perf trace' (Arnaldo Carvalho de Melo)

 - Fix divide by zero when calculating percent for an event in a group in
   the annotate by source line code (Taeung Song)

 - build-id files now aren't anymore symlinks, their parent directories
   are, so readlink the later (Taeung Song)

 - Assorted fixes for null termination problems, mostly related to
   readlink, detected by valgrind (Tommi Rantala)

Infrastructure changes:

 - Make vfs_getname probe point logic in 'perf trace' more robust
   wrt length of pathname (Arnaldo Carvalho de Melo)

 - Remove unused 'prefix' parameter from builtins main functions (Arnaldo Carvalho de Melo)

 - Show 'perf list sdt' option in man page (Ravi Bangoria)
