James Morse 8a695a5873 arm64: Kconfig: Remove ARCH_HAS_HOLES_MEMORYMODEL ... include/linux/mmzone.h describes ARCH_HAS_HOLES_MEMORYMODEL as relevant when parts the memmap have been free()d. This would happen on systems where memory is smaller than a sparsemem-section, and the extra struct pages are expensive. pfn_valid() on these systems returns true for the whole sparsemem-section, so an extra memmap_valid_within() check is needed. On arm64 we have nomap memory, so always provide pfn_valid() to test for nomap pages. This means ARCH_HAS_HOLES_MEMORYMODEL's extra checks are already rolled up into pfn_valid(). Remove it.
