Subject: [PATCH v2 07/12] riscv: Remove version check for LTO_CLANG selects
Date: Thu, 21 Aug 2025 14:15:44 -0700	[thread overview]
Message-ID: <20250821-bump-min-llvm-ver-15-v2-7-635f3294e5f0@kernel.org> (raw)
In-Reply-To: <20250821-bump-min-llvm-ver-15-v2-0-635f3294e5f0@kernel.org>

Now that the minimum supported version of LLVM for building the kernel
has been bumped to 15.0.0, there is no need to check the LLD version
before selecting ARCH_SUPPORTS_LTO_CLANG{,_THIN} because it will always
be true.

Small note, this will conflict with
https://lore.kernel.org/20250710-riscv-restrict-lto-to-medany-v1-1-b1dac9871ecf@kernel.org/
but I think it is simple enough to deal with.
