[PATCH 0/2] arm64: retry dropping HAVE_ARCH_PFN_VALID

2021-09-29 Thread Mike Rapoport
From: Mike Rapoport Hi, This is a new attempt to drop HAVE_ARCH_PFN_VALID on arm64 and start using the generic implementation of pfn_valid(). The first patch removes the check for pfn_valid() in dma_map_resource() which is required to avoid false positives when there is memory map for MMIO.
