From: Nathan Chancellor Date: Fri, 15 Aug 2025 01:31:42 +0000 (-0700) Subject: x86/Kconfig: Clean up LLVM version checks in IBT configurations X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=2c6a28f3ef729ed2d5b174b4e0f33172fb286bab;p=thirdparty%2Fkernel%2Fstable.git x86/Kconfig: Clean up LLVM version checks in IBT configurations The minimum supported version of LLVM for building the x86 kernel was bumped to 15.0.0 in 7861640aac52 ("x86/build: Raise the minimum LLVM version to 15.0.0"), so the checks for Clang 14.0.0 and ld.lld 14.0.0 or newer will always been true. Clean them up.
