  • Most of these fixes were already submitted for old kernel versions, and were
    approved, but for some reason they never made it into the releases.

    Because this is a consolidation of a couple old missed patches, it touches both
    Kconfigs and documentation texts.

  • This implements deferred IO support in fbdev. Deferred IO is a way to delay
    and repurpose IO. This implementation is done using mm's page_mkwrite and
    page_mkclean hooks in order to detect, delay and then rewrite IO. This
    functionality is used by hecubafb.

    This is useful for graphics hardware with no directly addressable/mappable
    framebuffer. Implementing this will allow the "framebuffer" to be accesible
    from user space via mmap().
