[PATCH] arch/x86/events - make more stuff static

[Valdis KlÄtnieks]

When building with C=2, sparse makes note of a number of things:

  CHECK   arch/x86/events/intel/rapl.c
arch/x86/events/intel/rapl.c:637:30: warning: symbol 'rapl_attr_update' was not declared. Should it be static?
  CHECK   arch/x86/events/intel/cstate.c
arch/x86/events/intel/cstate.c:449:30: warning: symbol 'core_attr_update' was not declared. Should it be static?
arch/x86/events/intel/cstate.c:457:30: warning: symbol 'pkg_attr_update' was not declared. Should it be static?
  CHECK   arch/x86/events/msr.c
arch/x86/events/msr.c:170:30: warning: symbol 'attr_update' was not declared. Should it be static?

And they can indeed be static.
