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"
