From 95b18ef9c69157ded5ece1136377cf8123b597f0 Mon Sep 17 00:00:00 2001 From: Pasha Tatashin Date: Sat, 13 Apr 2024 00:25:13 +0000 Subject: iommu/dma: use iommu_put_pages_list() to releae freelist Free the IOMMU page tables via iommu_put_pages_list(). The page tables were allocated via iommu_alloc_* functions in architecture specific places, but are released in dma-iommu if the freelist is gathered during map/unmap operations into iommu_iotlb_gather data structure. Currently, only iommu/intel that does that.
