[1/2] dma-mapping: remove bogus test for pfn_valid from dma_map_resource https://git.kernel.org/arm64/c/a9c38c5d267c [2/2] arm64/mm: drop HAVE_ARCH_PFN_VALID https://git.kernel.org/arm64/c/3de360c3fdb3 Cheers,
From: Mike Rapoport <rppt@linux.ibm.com> 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.
