Is there any reason why the recordmcount.pl would ever be used now that the

I notice that arch/arm/Kconfig has:

config ARM
...
        select HAVE_C_RECORDMCOUNT

so deprecating ARM support from recordmcount.pl seems unlikely to hurt
anyone.

The C implementation seems to have worked fine when I was testing dynamic
ftrace with Thumb-2 recently.

It's there only as a backup. But you're right. I may as well start
removing the recordmcount.pl support from those that have the
HAVE_C_RECORDMCOUNT set, and then all users are gone (which may now be
the case) either keep it around as a backup for testing against
recordmcount.c, or remove it completely.
