    Subject[PATCH 7/12] get_unmapped_area handles MAP_FIXED on parisc
    Handle MAP_FIXED in parisc arch_get_unmapped_area(), just return the
    address. We might want to also check for possible cache aliasing
    issues now that we get called in that case (like ARM or MIPS),
    leave a comment for the maintainers to pick up.
