spin_lock(&p->lock);

On a non-PREEMPT_RT kernel migrate_disable() maps to preempt_disable()
which makes the above code fully equivalent. On a PREEMPT_RT kernel
migrate_disable() ensures that the task is pinned on the current CPU which
in turn guarantees that the per-CPU access to var1 and var2 are staying on
the same CPU.
