The arch/arm/* stuff is all code that has been removed, but the pull
request didn't make it in time for v3.4:

   http://www.spinics.net/lists/arm-kernel/msg164545.html

Initially, this was intended as a cleanup because it was just dead code
removal, but since we missed v3.4, maybe we should pull out 
"ARM: OMAP: clock: cleanup CPUfreq leftovers" and submit for 3.4-rc.

This change was included in my CPUfreq pull request to Dave Jones.  He
has pulled it into his fixes branch[1], but I don't see it upstream.
I've just sent a mail to Dave asking about it.
