Comment 18 for bug 1708399

While preparing to provide a test kernel I noticed that the backport for patch #1 introduces a test for MACHINE_HAS_TLB_LC which is not present even in linux-next. Martin, is this really correct?

+ /* Reset TLB flush mask */
+ if (MACHINE_HAS_TLB_LC)
+ cpumask_copy(mm_cpumask(mm), &mm->context.cpu_attach_mask);
