From 0251d0107cfb0bb5ab2d3f97710487b9522db020 Mon Sep 17 00:00:00 2001 From: Lu Baolu Date: Wed, 19 Oct 2022 08:44:44 +0800 Subject: iommu: Add gfp parameter to iommu_alloc_resv_region Add gfp parameter to iommu_alloc_resv_region() for the callers to specify the memory allocation behavior. Thus iommu_alloc_resv_region() could also be available in critical contexts.
