Subject: [PATCH v20 2/7] riscv/Kconfig: make direct map manipulation options depend on MMU
Date: Tue, 18 May 2021 10:20:29 +0300 [thread overview]
Message-ID: <20210518072034.31572-3-rppt@kernel.org> (raw)
In-Reply-To: <20210518072034.31572-1-rppt@kernel.org>
From: Mike Rapoport <rppt@linux.ibm.com>
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.
