From bb1a54f7f011f19ed936632698eae574e0b91063 Mon Sep 17 00:00:00 2001 From: John Garry Date: Tue, 10 Feb 2026 19:31:12 +0800 Subject: LoongArch: Make cpumask_of_node() robust against NUMA_NO_NODE [ Upstream commit 94b0c831eda778ae9e4f2164a8b3de485d8977bb ] The arch definition of cpumask_of_node() cannot handle NUMA_NO_NODE - which is a valid index - so add a check for this.
