This is not usefull: it provides page->virtual and is used with
highmem. xtensa has no support for highmem and those HIGHMEM bits which are
found by grep are partly implemented. The interesting functions like kmap()
are missing. If someone actually implements the complete HIGHMEM support he
could use HASHED_PAGE_VIRTUAL like most others do.
