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.
Git tree:
git://git.infradead.org/users/hch/misc.git swiotlb-init-cleanup
Gitweb:
http://git.infradead.org/users/hch/misc.git/shortlog/refs/heads/swiotlb-init-cleanup
Changes since v1:
- skip IOMMU initialization on Xen PV kernels
- various small whitespace / typo fixes
