Subject: [RFC][PATCH 00/13] Cleanup recordmcount and begin objtool conversion

This series cleans up recordmcount and then makes it into
an objtool subcommand.

The series starts with 8 cleanup patches which make recordmcount
easier to review and integrate with objtool. The final 5 patches
show the beginning steps of converting recordmcount to use objtool's
ELF code rather than its own open-coded methods of accessing ELF
files.

Matt Helsley (13):
  recordmcount: Remove redundant strcmp
  recordmcount: Remove uread()
  recordmcount: Remove unused fd from uwrite() and ulseek()
  recordmcount: Rewrite error/success handling
  recordmcount: Kernel style function signature formatting
  recordmcount: Kernel style formatting
  recordmcount: Remove redundant cleanup() calls
  recordmcount: Clarify what cleanup() does
  objtool: Prepare to merge recordmcount
  objtool: Make recordmcount into an objtool subcmd
  objtool: recordmcount: Start using objtool's elf wrapper
  objtool: recordmcount: Search for __mcount_loc before walking the
    sections
  objtool: recordmcount: Convert do_func() relhdrs
