Message-Id: <20250821-bump-min-llvm-ver-15-v2-2-635f3294e5f0@kernel.org> Date: Thu, 21 Aug 2025 14:15:39 -0700 From: Nathan Chancellor <nathan@...nel.org> To: linux-kernel@...r.kernel.org Cc: Arnd Bergmann <arnd@...db.de>, Kees Cook <kees@...nel.org>, Nick Desaulniers <nick.desaulniers+lkml@...il.com>, Bill Wendling <morbo@...gle.com>, Justin Stitt <justinstitt@...gle.com>, llvm@...ts.linux.dev, patches@...ts.linux.dev, Nathan Chancellor <nathan@...nel.org>, linux-hardening@...r.kernel.org Subject: [PATCH v2 02/12] arch/Kconfig: Drop always true condition from RANDOMIZE_KSTACK_OFFSET Now that the minimum supported version of LLVM for building the kernel has been bumped to 15.0.0, the second depends line in RANDOMIZE_KSTACK_OFFSET is always true, so it can be removed.
