Subject: [PATCH 0/4] objtool,perf: Use shared x86 insn decoder

It's kind of silly that we have *three* identical copies of the x86 insn
decoder in the kernel tree.  Make it approximately 50% less silly by
reducing that number to two.

Josh Poimboeuf (4):
  objtool: Move x86 insn decoder to a common location
  perf: Update .gitignore file
  perf intel-pt: Remove inat.c from build dependency list
  perf intel-pt: Use shared x86 insn decoder
