Ah, stupid me. I was even on the Cc for David's patches. I missed
them, sorry.
David, why do we need two Kconfig symbols for mlock and the mlock page
bit? Don't we always provide mlock on mmu and never on nommu?
Anyway, that is just out of curiousity. Good that the change is
already done, so please ignore this patch.
Hannes
