#     KVM: PPC: Book3S HV: trace_tlbie must not be called in realmode
#     
#     This crashes with a "Bad real address for load" attempting to load
#     from the vmalloc region in realmode (faulting address is in DAR).
#     
#       Oops: Bad interrupt in KVM entry/exit code, sig: 6 [#1]

#     
#     I suspect the reason is the per-cpu data is not in the linear chunk.
#     This could be restored if that was able to be fixed, but for now,
#     just remove the tracepoints.
