[PATCH v2 1/6] arch_numa: simplify numa_distance allocation

[Mike Rapoport <rppt@kernel.org>]

From: Mike Rapoport <rppt@linux.ibm.com>

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().
