Subject: [PATCH 0/3] Alternatives vs ORC, a slightly easier way

These patches replace Peter's "Alternatives vs ORC, the hard way".  The
end result should be the same (support for paravirt patching's using of
alternatives which modify the stack).

Josh Poimboeuf (3):
  objtool: Refactor ORC section generation
  objtool: Add 'alt_group' struct
  objtool: Support stack layout changes in alternatives
