How about we start using the version field for this? Arguably we should
have incremented that value every time we changed the

OK, let me rephrase.
This change broke existing working code.
Can you point to any code that is fixed by the commit?
If not, I think the rule is you revert the changeset.
Or you

This patch somehow breaks the perf-ABI.
If I take a program that reads "mmap->cap_usr_rdpmc" and compile it
against the new header with this change (say from 3.12-rc1)
and then run it on an old kernel (say 3.11) then I get "0" for
cap_usr_rdpmc.
