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
