Merge tag 'perf-core-for-mingo' of... 

Merge tag 'perf-core-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

 into perf/core

Pull perf/core improvements and refactorings from Arnaldo Carvalho de Melo:

New features:

. In perf timechart:
	- Add backtrace support to CPU info
	. Print pid along the name
	. Add support for CPU topology
	. Add new option --highlight'ing threads, be it by name or,
	  if a numeric value is provided, that run more than given duration.
  From Stanislav Fomichev.

Refactorings:

. Rename some struct DSO binary_type related members and methods,
  to clarify its purpose and need for differentiation from symtab_type,
  i.e. one is about the files .text, CFI, etc, i.e. its binary contents,
  and the other is about where the symbol table came from.

. Convert to new topic libraries, starting with an API one (sysfs, debugfs,
  etc), renaming liblk in the process, from Borislav Petkov.

. Get rid of some more panic() like error handling in libtraceevent,
  from Namhyung Kim.
