powerpc/pseries: Optimize IOMMU setup The previous commit will use the page-at-a-time hypervisor call for setting up IOMMU entries when we are using 64k pages and setting up one 64k page, even though that means 16 calls to the hypervisor, since the hypervisor still works on 4k pages. This optimizes this case by using the multi-page IOMMU setup hypervisor call instead. Signed-off-by: Paul Mackerras <paulus@samba.org>
