   out of date, but will be faster.

   User programs should not refer to the contents of this structure.
   I repeat they should not refer to it. If they do they will break
   in future kernels.

   It is only a private cache for vgetcpu(). It will change in future kernels.
   The user program must store this information per thread (__thread)
   If you want 100% accurate information pass NULL instead. */
