If such functionality is indeed accepted upstream in Linux I see no reason
on not possible ack this patch (the ack it self will depend on patch
quality and architecture maintainer feedback). I see the idea is reasonable,
the only drawback is a slight large latency on program startup (due syscall
issuing in cacheinfo.c).

Before start to ask for patch revision, you need to sort out the copyright
by signing the papers with the FSF as pointed out by Mike Frysinger.
