From: Mike Rapoport <rppt@xxxxxxxxxxxxx> Subject: s390: remove ARCH_SELECT_MEMORY_MODEL The only reason s390 has ARCH_SELECT_MEMORY_MODEL option in arch/s390/Kconfig is an ancient compile error with allnoconfig which was fixed by commit 97195d6b411f ("[S390] fix sparsemem related compile error with allnoconfig on s390") by adding the ARCH_SELECT_MEMORY_MODEL option. Since then a lot have changed and now allnoconfig builds just fine without ARCH_SELECT_MEMORY_MODEL, so it can be removed.
