    Subject[PATCH] ARM: MSM: Fix early debug uart mapping on some memory configs
    The uart mapping runs into the space allocated for lowmem on some
    8960 boards when we have more than 512Mb of memory. We were
    getting lucky before and our mapping wasn't part of DDR. Move the
    mapping up into the vmalloc area which will always be outside of
    the lowmem mapping regardless of how much lowmem actually exists.
