Subject: [PATCH 3/6] kbuild: Keep PCI fixups through dead code elimination
Date: Thu, 20 Oct 2016 21:27:02 +0100	[thread overview]
Message-ID: <20161020202705.3783-4-paul.burton@imgtec.com> (raw)
In-Reply-To: <20161020202705.3783-1-paul.burton@imgtec.com>

With CONFIG_LD_DEAD_CODE_DATA_ELIMINATION enabled we must ensure that we
keep PCI fixups or they will be discarded during the link & we'll lose
support for any PCI fixups.
