    Updated patchset follows.

    Most importantly, the first patch has been replaced by the one adding
    __GFP_NO_OOM_KILL, following the Andrew's advice. The other patches are
    slightly changed to address some comments I've received since yesterday.

    Please tell me what you think.

    Best,
    Rafael
