Subject: cleanup swiotlb initialization
Date: Tue, 22 Feb 2022 16:35:03 +0100 [thread overview]
Message-ID: <20220222153514.593231-1-hch@lst.de> (raw)
Hi all,
this series tries to clean up the swiotlb initialization, including
that of swiotlb-xen. To get there is also removes the x86 iommu table
infrastructure that massively obsfucates the initialization path.
