Subject: [PATCH 10/12] arm: don't build swiotlb by default
Date: Mon, 23 Apr 2018 19:04:17 +0200 [thread overview]
Message-ID: <20180423170419.20330-11-hch@lst.de> (raw)
In-Reply-To: <20180423170419.20330-1-hch@lst.de>
swiotlb is only used as a library of helper for xen-swiotlb if Xen support
is enabled on arm, so don't build it by default.
