Subject: [PATCH 3/3] sparc: remove ARCH_SELECT_MEMORY_MODEL

The ARCH_SELECT_MEMORY_MODEL option is enabled only for 64-bit. However,
64-bit configuration also enables ARCH_SPARSEMEM_DEFAULT and there is no
ARCH_FLATMEM_ENABLE in arch/sparc/Kconfig.

With such settings, the dependencies in mm/Kconfig are always evaluated to
SPARSEMEM=y for 64-bit and to FLATMEM=y for 32-bit.

The ARCH_SELECT_MEMORY_MODEL option in arch/sparc/Kconfig does not affect
anything and can be removed.
