Title
LoongArch: Make cpumask_of_node() robust against NUMA_NO_NODE
Summary
In the Linux kernel, the following vulnerability has been resolved:

Where a specific path is admin-only, the macro bug itself is still reachable through normal local kernel-facing interfaces, so the higher-severity PR:L is selected.\nUI:N - No victim user action is needed beyond the attacker invoking the local interface.\nS:U - The impact remains within the kernel and its managed resources; there is no guest-to-host, IOMMU, or other separate security authority boundary crossing.\nC:H - The bug is an out-of-bounds read of a cpumask object before the cpus_on_node array, and cpumask data may be exposed or used through sysfs/perf-style paths.\nI:H - The invalid cpumask pointer can be consumed by cpumask helpers and affinity-setting paths, and an array-underflow kernel memory access is treated as potentially enabling corruption or control of kernel decisions.\nA:H - Invalid cpumask access can produce UBSAN/oops/panic behavior or destabilize kernel CPU-affinity handling, giving high availability impact."
