From: Mike Rapoport <redacted>
Memory allocation of numa_distance uses memblock_phys_alloc_range() without
actual range limits, converts the returned physical address to virtual and
then only uses the virtual address for further initialization.
Simplify this by replacing memblock_phys_alloc_range() with
memblock_alloc().
