The current implementation of per_cpu relies on several non-c99 features, and in additional involves arbitrary pointer arithmetic which is not MIS- RA C friendly. This patch introduces struct per_cpu_region which holds all the per_cpu variables. Allocation of per_cpu data regions and access to per_cpu vari- ables are greatly simplified, at the cost of making all per_cpu varaibl- es accessible in files.
