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.
