    Subject[PATCH v5 7/7] sh: mm: set VM_IOREMAP flag to the vmalloc area
    Date
    Currently, for vmalloc areas with flag VM_IOREMAP set, except of the
    specific alignment clamping in __get_vm_area_node(), they will be
    1) Shown as ioremap in /proc/vmallocinfo;
    2) Ignored by /proc/kcore reading via vread()

    So for the ioremap in __sq_remap() of sh, we should set VM_IOREMAP
    in flag to make it handled correctly as above.
