Subject: [PATCH] kernel/events/core.c - make perf_swevent_init_cpu static

'make W=1' causes a gcc complaint:

  CC      kernel/events/core.o
kernel/events/core.c:11877:6: warning: no previous prototype for 'perf_swevent_init_cpu' [-Wmissing-prototypes]
11877 | void perf_swevent_init_cpu(unsigned int cpu)
      |      ^~~~~~~~~~~~~~~~~~~~~

It's not referenced anyplace else, make it static.

(Other unrelated warnings elided for clarity)
