This would appear to be a page which was mapped by remap_page_range(). It's not PageReserved, and it has no reverse mapping. I believe the right fix is to just delete the BUG check at rmap.c:280.

Rik, that's right, isn't it? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
