From 3951c41af4a65ba418e6b1b973d398552bedb84f Mon Sep 17 00:00:00 2001 From: Will Deacon Date: Tue, 2 Jul 2019 16:45:15 +0100 Subject: iommu/io-pgtable: Pass struct iommu_iotlb_gather to ->tlb_add_page() With all the pieces in place, we can finally propagate the iommu_iotlb_gather structure from the call to unmap() down to the IOMMU drivers' implementation of ->tlb_add_page(). Currently everybody ignores it, but the machinery is now there to defer invalidation.
