From 00c376fdd7ed6cc083da3a3c51a63a75f270d647 Mon Sep 17 00:00:00 2001 From: Alexey Kardashevskiy Date: Mon, 2 Jul 2018 17:42:05 +1000 Subject: [PATCH] powerpc/powernv/ioda2: Add 256M IOMMU page size to the default POWER8 case The sketchy bypass uses 256M pages so add this page size as well. This should cause no behavioral change but will be used later.
