Aneesh Kumar K.V 22259a6e80 powerpc/mm/cxl: Add barrier when setting mm cpumask ... We need to add memory barrier so that the page table walk doesn't happen before the cpumask is set and made visible to the other cpus. We need to use a sync here instead of lwsync because lwsync is not sufficient for store/load ordering. We also need to add an if (mm) check so that we do the right thing when called with a kernel context. For kernel context, we have mm = NULL. W.r.t kernel address we can skip setting the mm cpumask.
