      sparc64: Fix bit twiddling in sparc_pmu_enable_event(). · e793d8c6
      David S. Miller authored
      There was a serious disconnect in the logic happening in
      sparc_pmu_disable_event() vs. sparc_pmu_enable_event().
      
      Event disable is implemented by programming a NOP event into the PCR.
      
      However, event enable was not reversing this operation.  Instead, it
      was setting the User/Priv/Hypervisor trace enable bits.
      
      That's not sparc_pmu_enable_event()'s job, that's what
      sparc_pmu_enable() and sparc_pmu_disable() do .
      
      The intent of sparc_pmu_enable_event() is clear, since it first clear
      out the event type encoding field.  So fix this by OR'ing in the event
      encoding rather than the trace enable bits.
