Subject: [PATCH 0/2] arm64: retry dropping HAVE_ARCH_PFN_VALID

From: Mike Rapoport <rppt@...ux.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.

Anshuman Khandual (1):
  arm64/mm: drop HAVE_ARCH_PFN_VALID

Mike Rapoport (1):
  dma-mapping: remove bogus test for pfn_valid from dma_map_resource
