From f34ce7a7018c2f71d78fc7f512f6daf01e487114 Mon Sep 17 00:00:00 2001 From: Baolin Wang Date: Fri, 12 Jun 2020 11:39:55 +0800 Subject: iommu: Add gfp parameter to io_pgtable_ops->map() Now the ARM page tables are always allocated by GFP_ATOMIC parameter, but the iommu_ops->map() function has been added a gfp_t parameter by commit 781ca2de89ba ("iommu: Add gfp parameter to iommu_ops::map"), thus io_pgtable_ops->map() should use the gfp parameter passed from iommu_ops->map() to allocate page pages, which can avoid wasting the memory allocators atomic pools for some non-atomic contexts.
