Subject: [PATCH 08/14] riscv: Remove tautological condition from selection of ARCH_SUPPORTS_CFI
Date: Tue, 28 Apr 2026 22:59:14 -0400 [thread overview]
Message-ID: <20260428-bump-minimum-supported-llvm-version-to-17-v1-8-81d9b2e8ee75@kernel.org> (raw)
In-Reply-To: <20260428-bump-minimum-supported-llvm-version-to-17-v1-0-81d9b2e8ee75@kernel.org>
Now that the minimum supported version of LLVM for building the kernel
has been raised to 17.0.1, the condition of the selection of
CONFIG_ARCH_SUPPORTS_CFI is always true, so it can be removed.
