# Merge: 97d8cc20085f 3eb9cdffb397
# Author: Linus Torvalds <torvalds@linux-foundation.org>
# Date:   Thu Aug 26 11:26:00 2021 -0700
# 
#     Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
#     
#     Pull arm64 fix from Will Deacon:
#      "We received a report this week that the generic version of
#       pfn_valid(), which we switched to this merge window in 16c9afc77660
#       ("arm64/mm: drop HAVE_ARCH_PFN_VALID"), interacts badly with
#       dma_map_resource() due to the following check:
#     
#             /* Don't allow RAM to be mapped */
#             if (WARN_ON_ONCE(pfn_valid(PHYS_PFN(phys_addr))))
#                     return DMA_MAPPING_ERROR;
#     
#       Since the ongoing saga to determine the semantics of pfn_valid() is
#       unlikely to be resolved this week (does it indicate valid memory, or
#       just the presence of a struct page, or whether that struct page has
#       been initialised?), just revert back to our old version of pfn_valid()
#       for 5.14.
#     
#       Summary:
#     
#        - Fix dma_map_resource() by reverting back to old pfn_valid() code"
