Subject: [PATCH 02/11] Makefile: Drop warn-stack-size plugin opt
Date: Thu, 25 Jan 2024 15:55:08 -0700	[thread overview]
Message-ID: <20240125-bump-min-llvm-ver-to-13-0-1-v1-2-f5ff9bda41c5@kernel.org> (raw)
In-Reply-To: <20240125-bump-min-llvm-ver-to-13-0-1-v1-0-f5ff9bda41c5@kernel.org>

Now that the minimum supported version of LLVM for building the kernel
has been bumped to 13.0.1, the inner ifeq statement is always false, as
the build will fail during the configuration stage for older LLVM
versions.

This effectively reverts commit 24845dcb170e ("Makefile: LTO: have
linker check -Wframe-larger-than") and its follow up fix,
commit 0236526d76b8 ("Makefile: lto: Pass -warn-stack-size only on LLD <
13.0.0").
