[PATCH] Fix smp_processor_id() warning in numa_node_id()
The patch below fixes smp_processor_id() warnings that are triggered by
numa_node_id().
All uses of numa_node_id() in mm/mempolicy.c seem to use it as a 'hint'
only, not as a correctness number. Once a node is established, it's used
in a preemption-safe way. So the simple fix is to disable the checking for
numa_node_id(). But additional review would be more than welcome, because
this patch turns off the preemption-checking of numa_node_id() permanently.
Tested on amd64.
