[Xen-devel] [PATCH v4 1/3] xen/arm: Re-order iommu_setup to after setup_virt_paging

["Edgar E. Iglesias" <edgar.iglesias@xxxxxxxxx>]

From: "Edgar E. Iglesias" <edgar.iglesias@xxxxxxxxxx>

This is needed to allow the paging setup to probe for
IPA bit sizes to be used in p2m tables prior to iommu setup.
