Subject: [PATCH 09/15] binfmt_flat: add a ARCH_HAS_BINFMT_FLAT option
Date: Mon, 10 Jun 2019 21:20:09 +0000 [thread overview]
Message-ID: <20190610212015.9157-10-hch@lst.de> (raw)
In-Reply-To: <20190610212015.9157-1-hch@lst.de>
Allow architectures to opt into ARCH_HAS_BINFMT_FLAT support instead of
assuming that all nommu ports support the format.
