Subject[PATCH 07/15] riscv: drop unneeded node initialization
Date
From: Mike Rapoport <rppt@linux.ibm.com>

RISC-V does not (yet) support NUMA and for UMA architectures node 0 is
used implicitly during early memory initialization.

There is no need to call memblock_set_node(), remove this call and the
surrounding code.
