Subject: [PATCH v2 06/17] riscv: drop unneeded node initialization
Date: Sun, 2 Aug 2020 19:35:50 +0300 [thread overview]
Message-ID: <20200802163601.8189-7-rppt@kernel.org> (raw)
In-Reply-To: <20200802163601.8189-1-rppt@kernel.org>
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.
