Subject: [PATCH v2 0/2] cpufreq / sched: Rework of cpufreq_update_util() arguments

Hi,

There were some comments on the "cpufreq / sched: cpufreq_update_util() flags
and iowait boosting" series I sent some time ago and I wanted to address them,
but for this purpose I had to combine patches [1-2,4/7] from that series
into one and make some changes on top of that.

Then I thought it would be better to send that separately from the iowait
boost part of that series, so here it goes.

[1/2] Removes the util and max args from cpufreq_update_util() and governor
      callbacks and adds a flags argument instead of them.  That argument
      is then used to handle RT and DL in schedutil and the utilization data
      are accessed by it directly (so it is non-modular now to avoid exporting
      the scheduler internals to modules).
[2/2] Replaces the time argument of cpufreq_update_util() with an rq pointer
      which allows some simplifications to be made.

There should be no changes in behavior as a result of this.

The v2 is to address comments from Steve.

Thanks,
Rafael
