MISRA C required that return value should be used, missing for it should
add "(void)" prefix before the function call.
Some function can be declared without return value to avoid this problem.

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.

Add timer would not schedule timer unless it's the next
timer event.
