[PATCH][2.6.11-mm3] perfctr API update 6/9: cpu_control access, common

[Mikael Pettersson]

- Add declarations of common arch-specific domain numbers and
  corresponding data structures to <linux/perfctr.h>. This just
  factors out common code, it does not impose any requirements
  on arch-specific code.
