Subject: objtool: Print top level commands on incorrect usage

From: Kamalesh Babulal <[email protected]>

commit 6a93bb7e4a7d6670677d5b0eb980936eb9cc5d2e upstream.

Print top-level objtool commands, along with the error on incorrect command line usage. Objtool command line parser exit's with code 129, for incorrect usage. Convert the cmd_usage() exit code also, to maintain consistency across objtool.

After the patch:

  $ ./objtool -j

Unknown option: -j

usage: objtool COMMAND [ARGS]

Commands:
check Perform stack metadata validation on an object file
orc Generate in-place ORC unwind tables for an object file

  $ echo $?
  129
