This is the exact opposite of what I'd hoped come of this discussion. ISTR something about remap_area_pages() missing several pieces, but I pretty much need some kind of clarification to know what. Well, that, and I presumed your fixups for ALSA were headed toward mainline regardless after coping with whatever issue dwmw2 had (e.g. returning pfn's or something).
