x86: set_highmem_pages_init() cleanup, #2
Impact: cleanup The zones are set up at this stage so there's a highmem zone available even for the UMA case. The only difference there is that for machines that have CONFIG_HIGHMEM enabled but don't have any highmem available, ->zone_start_pfn is zero whereas highstart_pfn is non-zero). The field is left zeroed because of the !size test in free_area_init_core() but shouldn't be a problem because add_highpages_with_active_regions() handles empty ranges just fine.
