Subject: [PATCH 1/3] arm: remove ARCH_SELECT_MEMORY_MODEL
Date: Wed, 1 May 2019 22:56:15 +0300 [thread overview]
Message-ID: <1556740577-4140-2-git-send-email-rppt@linux.ibm.com> (raw)
In-Reply-To: <1556740577-4140-1-git-send-email-rppt@linux.ibm.com>
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.
