   5  * To calculate addresses of locally defined variables, GCC uses
   6  * 32-bit displacement from the GP. Which doesn't work for per cpu
   7  * variables in modules, as an offset to the kernel per cpu area is
   8  * way above 4G.
   9  *
  10  * Always use weak definitions for percpu variables in modules.
