they are wrappers for core versions. they are taking start/end/name instead of base/size. could add more debug print out -v2: change get_max_mapped() to lmb.default_alloc_limit according to Michael Ellerman and Ben change to lmb_reserve_area and lmb_free_area according to Michael Ellerman -v3: call check_and_double after reserve/free, so could avoid to use find_lmb_area.
