Subject: [PATCH 0/2] arm64, numa: Fix OOPS with numa=off

From: David Daney <david.daney@...ium.com>

We get an OOPS in the arm64 kernel on NUMA systems when numa=off is
passed on the command line.

Fix it by returning NUMA_NO_NODE from of_node_to_nid when numa=off.

David Daney (2):
  of, numa: Add function to disable of_node_to_nid().
  arm64, numa: Force of_node_to_nid to return NUMA_NO_NODE when
    numa=off.
