I thought it was supposed to work because the kernel-doc scripts were at the
time taught by commit 51a7bf0238c2 ("scripts/kernel-doc: drop "_noprof" on
function prototypes") to handle _noprof. In the current form git grep finds:

tools/lib/python/kdoc/kdoc_parser.py: suffixes = [ '_noprof' ]
tools/lib/python/kdoc/xforms_lists.py: (KernRe("_noprof"), ""),

Doesn't it work for you then?
