[PATCH v2 0/2] objtool: add support for >64k sections

[Sami Tolvanen]

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.

Changes in v2:
 - Dropped the insn_hash optimization as Peter has a nearly
   similar change queued already.
 - Instead of storing the last instruction for each section,
   use find_insn to locate it.


Sami Tolvanen (2):
  objtool: use gelf_getsymshndx to handle >64k sections
  objtool: optimize add_dead_ends for split sections
