Subject: [PATCH 2/6] kbuild: Keep .init.setup section through dead code elimination
Date: Thu, 20 Oct 2016 21:27:01 +0100	[thread overview]
Message-ID: <20161020202705.3783-3-paul.burton@imgtec.com> (raw)
Message-ID: <20161020202701.rmjdRSRtZw7k2xqYFl7s2qFMo8_YKpOUQSfK4N_YRYo@z> (raw)
In-Reply-To: <20161020202705.3783-1-paul.burton@imgtec.com>

With CONFIG_LD_DEAD_CODE_DATA_ELIMINATION we must keep the .init.setup
section or we'll throw away support for kernel parameters.
