    Hi Wu,

    I think we can use MAX_DMA_PFN and MAX_DMA32_PFN to prevent setting DMA
    address as movable. Just ignore the address lower than them, and set
    the rest as movable. How do you think ?

    And, since we cannot figure out the minimum of memory kernel needs, I
    think for now, we can just add some warning into kernel-parameters.txt.

    Thanks. :)
