cool options.
<Aside>

Im seeing the err/warn counts change along with use of those options.
not a big deal, but it is mildly surprising
forex:
$ scripts/checkpatch.pl -f include/asm-generic/vmlinux.lds.h --terse
...
total: 18 errors, 7 warnings, 1164 lines checked
$ scripts/checkpatch.pl -f include/asm-generic/vmlinux.lds.h --terse --strict
...
total: 9 errors, 7 warnings, 95 checks, 1164 lines checked
