    get_user_pages() is screwed, I'm just not sure
    about failing get_user_pages() if PageReserved page
    is encountered.

    I'm more worried about make_pages_present(), which is
    called by find_extend_vma/do_mmap_pgoff. Is it valid
    to have PageReserved pages on the zones handled
    by these functions anyway?

    This is equivalent of Andrea's fix for mainline.

    Andrea, this in SuSE's tree for a while correct?
