Linus Torvalds b6fd9e2594 arm: ioremap: don't abuse pfn_valid() to check if pfn is in RAM 
The semantics of pfn_valid() is to check presence of the memory map for a
 PFN and not whether a PFN is in RAM. The memory map may be present for a
 hole in the physical memory and if such hole corresponds to an MMIO range,
 __arm_ioremap_pfn_caller() will produce a WARN() and fail:
 
 Use memblock_is_map_memory() instead of pfn_valid() to check if a PFN is in
 RAM or not.

Merge tag 'fixes-2021-07-09' of git://git.kernel.org/pub/scm/linux/kernel/git/rppt/memblock

Pull memblock fix from Mike Rapoport:
 "This is a fix for the rework of ARM's pfn_valid() implementation
  merged during this merge window.

  Don't abuse pfn_valid() to check if pfn is in RAM

  The semantics of pfn_valid() is to check presence of the memory map
  for a PFN and not whether a PFN is in RAM. The memory map may be
  present for a hole in the physical memory and if such hole corresponds
  to an MMIO range, __arm_ioremap_pfn_caller() will produce a WARN() and
  fail.

  Use memblock_is_map_memory() instead of pfn_valid() to check if a PFN
  is in RAM or not"
