Subject: [pchecks v2 0/2] percpu v2: Implement Preemption checks for __this_cpu operations

This patchset introduces preemption checks for __this_cpu operations.

First we add new raw_cpu operations that perform this cpu operations
without preempt checks. 

The second patch then adds the preempt checks by modifying the
__this_cpu macros in include/linux/percpu.h

V1->V2:
	- Reuse preemption check logic in lib/smp_processor_id.c
	- Add CONFIG_DEBUG_THIS_CPU_OPERATIONS
	- Remove conversions to the use of raw_cpu_ops since
	  these may require some discussion first.
