The only places where things might care is arch bootup code, but

Please see i386 patch. it contains BUG fix.
cpu_msrs[i].coutners are allocated by for_each_online_cpu().
and free it by for_each_possible_cpus() without no pointer check.


Well that's another problem then, such a fix should not be sent in
this patchset, but as a separate patch.

I think this kind of confusion will be seen again in future.

I'm sure that renaming for_each_cpu would not prevent that either.
