[PATCH 15/41] mm: Use raw_cpu ops for determining current NUMA node

[Patch depends on another patch in this series that introduces raw_cpu_ops] With the preempt checking logic for __this_cpu_ops we will get false positives from locations in the code that use numa_node_id. Before the __this_cpu ops where introduced there were no checks for preemption present eith
