Merge branch 'core-objtool-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull objtool updates from Ingo Molnar:
 "This is an extensive rewrite of the objdump tool to track all stack
  pointer modifications through the machine instructions of disassembled
  functions found in kernel .o files.

  This re-design removes the prior dependency on CONFIG_FRAME_POINTERS,
  with the goal to prepare the tool to generate kernel debuginfo data in
  the future. There's also an increase in checking/tracking robustness
  as a side effect as well.

  No (intended) changes to existing functionality"
