Enable high memory
* i386/i386at/biosmem.c (biosmem_setup): Load the HIGHMEM segment if
present.
(biosmem_free_usable): Report high memory as usable.
* vm/vm_page.c (vm_page_boot_table_size, vm_page_table_size,
vm_page_mem_size, vm_page_mem_free): Scan all segments.
* vm/vm_resident.c (vm_page_grab): Describe allocation strategy
with regard to the HIGHMEM segment.
