I had previously sent them to Michal and cc:kbuild, but Michal has not
picked them up yet hence I've sent them to lkml now.
It's not clear to me if Michal is the person responsible for
recordmcount changes, but I initially posted this to kbuild as this is
where all of your dead code & data elimination patches were going through.

Michal - do you plan to pick up these changes or would they need to be
acked/merged by somebody else?

thanks,
Marcin
