Those aren't tracepoints; they're deprecated debug statistics.

For tracepoints, see

   include/trace/events/kvm.h (general kvm tracepoints)
   arch/powerpc/kvm/trace.h (ppc specific tracepoints)
   arch/powerpc/kvm/book3s_mmu_hpte.c (examples of use, look for 
trace_kvm_*)
   Documentation/trace/tracepoints.txt (documentation, likely outdated)
