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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
