Umm. I think we should remove CONFIG_OPROFILE entirely, and then
dcookies as part of it.

We discussed removing CONFIG_OPROFILE for 5.9 (I htink) already - the
oprofile user land tools don't use the kernel OPROFILE support any
more, and haven't in a long time. User land has been converted to the
perf interfaces.
