From: Mike Rapoport <redacted> 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. Signed-off-by: Mike Rapoport <redacted> --- arch/riscv/mm/init.c | 9 --------- 1 file changed, 9 deletions(-)
