Subject: [PATCH 0/3] objtool: add support for >64k sections

This series fixes objtool for binaries with >64k sections, and
includes optimizations to reduce the runtime for a binary with
~130k sections from >15 minutes to ~4 seconds.

Sami Tolvanen (3):
  objtool: use gelf_getsymshndx to handle >64k sections
  objtool: optimize insn_hash for split sections
  objtool: optimize add_dead_ends for split sections
