From 03069bb0b19f8c3b6e079099dd8ac5e974756381 Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Thu, 11 Jul 2019 20:54:24 -0700 Subject: arm: remove ARCH_SELECT_MEMORY_MODEL Patch series "remove ARCH_SELECT_MEMORY_MODEL where it has no effect". For several architectures the ARCH_SELECT_MEMORY_MODEL has no real effect because the dependencies for the memory model are always evaluated to a single value. Remove the ARCH_SELECT_MEMORY_MODEL from the Kconfigs for these architectures. This patch (of 3): The ARCH_SELECT_MEMORY_MODEL in arch/arm/Kconfig is enabled only when ARCH_SPARSEMEM_ENABLE=y. But in this case, ARCH_SPARSEMEM_DEFAULT is also enabled and this in turn enables SPARSEMEM_MANUAL. Since there is no definition of ARCH_FLATMEM_ENABLE in arch/arm/Kconfig, SPARSEMEM_MANUAL is the only enabled memory model, hence the final selection will evaluate to SPARSEMEM=y. Since ARCH_SPARSEMEM_ENABLE is set to 'y' only by several sub-arch configurations, the default for must sub-arches would be the falback to FLATMEM regardless of ARCH_SELECT_MEMORY_MODEL.
