Merge tag 'perf-core-for-mingo-4.17-20180323' of git://git.kernel.org/pub/scm/linux...

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

- Move non-TUI specific annotation routines out of the TUI browser so
  that it can be used in other UIs, and to demonstrate that introduce
  a 'perf annotate --stdio2' option that will apply those formatting
  routines to provide a non-interactive annotation mode (Arnaldo Carvalho de Melo)

- Add 'P' hotkey to the annotation TUI, so dump the current annotated
  symbol to a file, easing report thru e-mail, by getting rid of the
  spaces + right hand side scrollbar chars (Arnaldo Carvalho de Melo)

- Support --ignore-vmlinux to 'perf report' and 'perf annotate', that
  was already present in 'perf top', to use /proc/{kcore,kallsyms},
  allowing to see what is in fact running (patched stuff, alternatives,
  ftrace, etc), not the initial state of the kernel (vmlinux) (Arnaldo Carvalho de Melo)

- Support 'jump' instructions to a different function, treating them
  as 'call' instructions (Arnaldo Carvalho de Melo)

- Fix some jump artifacts when using vmlinux + ASM functions, where
  the ELF symtab for instance, for entry_SYSCALL_64 includes that and
  what comes after the 'syscall_return_via_sysret' label, but the
  objdump -dS prints the jump targets + offsets using the
  syscall_return_via_sysret address, which was confusing 'perf annotate'.
  See the cset comments for further info (Arnaldo Carvalho de Melo)

- Report error from dwfl_attach_state() in the unwind code (Martin Vuille)

- Reference Py_None before returning it in the python extension (Petr Machata)
