From mboxrd@z Thu Jan 1 00:00:00 1970 From: Mike Rapoport Subject: [PATCH 1/3] arm: remove ARCH_SELECT_MEMORY_MODEL Date: Wed, 1 May 2019 22:56:15 +0300 Message-ID: <1556740577-4140-2-git-send-email-rppt@linux.ibm.com> References: <1556740577-4140-1-git-send-email-rppt@linux.ibm.com> Return-path: In-Reply-To: <1556740577-4140-1-git-send-email-rppt@linux.ibm.com> Sender: linux-kernel-owner@vger.kernel.org To: Andrew Morton Cc: Arnd Bergmann , Christoph Hellwig , "David S.

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.
