Function signature looks good.
But on a platform with firmware based memory retaining facilitites
we're going to need to invoke this way before bootmem or memblocks are
even setup, because the retain call influences the free memory lists
that the firmware gives to us and those free memory lists are what we
use to populate the memblock tables.
