range_new doesn't seem to be used after init. It is only passed to memset, sum_ranges, memcmp and x86_get_mtrr_mem_range, the latter of which also only passes it on to various *range* library functions. So mark it __initdata to free up an extra page after init.
nr_range_new is unconditionally assigned to before it is read, so there's no point in having it static.
