    PM / tracing: remove deprecated power trace API · 43720bd6
    Paul Gortmaker authored
    The text in Documentation said it would be removed in 2.6.41;
    the text in the Kconfig said removal in the 3.1 release.  Either
    way you look at it, we are well past both, so push it off a cliff.
    Note that the POWER_CSTATE and the POWER_PSTATE are part of the
    legacy tracing API.  Remove all tracepoints which use these flags.
    As can be seen from context, most already have a trace entry via
    trace_cpu_idle anyways.
    Also, the cpufreq/cpufreq.c PSTATE one is actually unpaired, as
    compared to the CSTATE ones which all have a clear start/stop.
    As part of this, the trace_power_frequency also becomes orphaned,
    so it too is deleted.
