Message-Id: <20240417-x86-fix-kexec-with-llvm-18-v1-2-5383121e8fb7@kernel.org> Date: Wed, 17 Apr 2024 14:53:46 -0700 From: Nathan Chancellor <nathan@...nel.org> To: tglx@...utronix.de, mingo@...hat.com, bp@...en8.de, dave.hansen@...ux.intel.com Cc: x86@...nel.org, hpa@...or.com, ndesaulniers@...gle.com, morbo@...gle.com, justinstitt@...gle.com, song@...nel.org, ribalda@...omium.org, linux-kernel@...r.kernel.org, llvm@...ts.linux.dev, patches@...ts.linux.dev, Nathan Chancellor <nathan@...nel.org> Subject: [PATCH 2/2] x86/purgatory: Enable orphan section warnings Now that the purgatory has a linker script that explicitly describes all of its sections, turn on orphan section warnings for it so that new sections do not appear without notice.
