We never did dynamic PAGE_OFFSET because we _had_ taken the decision with the inclusion of XIP support that we weren't going to have self-modifying code in the kernel - and loading the offset for every page table walk would have been very expensive. The self-modifying code viewpoint seems to have changed as a result of Nicolas moving jobs, from an employer who wanted XIP to one who wants a single kernel image, which in itself isn't surprising. _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
