Where is memory handed out?

    Hi!

    I'm working on a memory subsystem patch to deal with faulty RAM, for
    instance caused by static electricity or production failures. I have
    everything in place and working except for one thing: Avoiding that the
    faulty pages can get allocated.

    There must be a place where physical memory, after chunks are taken off of
    the beginning (for page maps etc), actually are handed out to the free_area
    structures, through something like __free_pages. But that routine does not
    seem to be called from such code, and neither are the remap routines (only
    called from drivers).

    Can anybody tell me where/how the "whole" of physical memory is handed over
    to the free_area structures?

    Thanx a lot,
    -Rick.
