    fbdev: defio and Metronomefb · de7c6d15

    Implement support for the E-Ink Metronome controller.  It provides an mmapable
    interface to the controller using defio support.  It was tested with a gumstix
    pxa255 with Vizplex media using Xfbdev and various X clients such as xeyes,
    xpdf, xloadimage.
    This patch also fixes the following bug: Defio would cause a hang on write
    access to the framebuffer as the page fault would be called ad-infinitum.  It
    fixes fb_defio by setting the mapping to be used by page_mkclean.
