From: Mike Rapoport <rppt@xxxxxxxxxxxxx> Subject: riscv/Kconfig: make direct map manipulation options depend on MMU ARCH_HAS_SET_DIRECT_MAP and ARCH_HAS_SET_MEMORY configuration options have no meaning when CONFIG_MMU is disabled and there is no point to enable them for the nommu case. Add an explicit dependency on MMU for these options.
