Subject: [PATCH 03/17] binfmt_flat: provide a default version of flat_get_relocate_addr
Date: Thu, 13 Jun 2019 09:08:49 +0200	[thread overview]
Message-ID: <20190613070903.17214-4-hch@lst.de> (raw)
In-Reply-To: <20190613070903.17214-1-hch@lst.de>

This way only the two architectures that do masking need to provide
the helper.
