    The first patch in this series (assuming I'm driving git-send-email
    correctly) adds the io_mapping API. I ended up creating a new
    linux/io_mapping.h file as the kernel init code uses io.h and got very angry
    when I tried to include linux/highmem.h from that. I'm afraid I gave up at
    that point and just moved the code to a new file.

    The second patch switches the drm/i915 driver to the new API. Performance
    improvements on 64-bit kernels are impressive as we were using the slow path
    before and now get to take advantage of 64-bit wonderfulness.
