Thanks for the pointing me.
Maybe we need change it with following as.

  void flush_icache_page(struct vm_area_struct *vma, struct page *page)
        All the functionality of flush_icache_page can be implemented in
        flush_dcache_page or __sync_icache_dcache in set_pte_ext(ex
ARM), update_mmu_cache and set_pte_at. In 2.7 the hope is to
        remove this interface completely.
