Subject: [PATCH 0/2] arm64: retry dropping HAVE_ARCH_PFN_VALID
Date: Thu, 30 Sep 2021 04:30:37 +0300	[thread overview]
Message-ID: <20210930013039.11260-1-rppt@kernel.org> (raw)

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.

  arm64/mm: drop HAVE_ARCH_PFN_VALID

  dma-mapping: remove bogus test for pfn_valid from dma_map_resource
