Subject: [PATCH V2 0/7] cpufreq: governors: Fix ABBA lockups

Hi Rafael,

Here is the V2 with updated patches as suggested by you guys.

These are pushed here:
git://git.kernel.org/pub/scm/linux/kernel/git/vireshk/pm.git cpufreq/governor-kobject

The first four patches are for 4.5, if possible and others you can keep
for 4.6.

V1->V2:
- Improved changelogs, thanks Rafael.
- Added new dbs_data->mutex to avoid concurrent updates to tunables.
- Moved kobj_type to common_dbs_data.
- Updated macros to static inline routines
- s/show/governor_show
- s/store/governor_store
- Improved comments

@Juri: More testing requested :)

Viresh Kumar (7):
  cpufreq: governor: Treat min_sampling_rate as a governor-specific
    tunable
  cpufreq: governor: New sysfs show/store callbacks for governor
    tunables
  cpufreq: governor: Drop unused macros for creating governor tunable
    attributes
  Revert "cpufreq: Drop rwsem lock around CPUFREQ_GOV_POLICY_EXIT"
  cpufreq: Merge cpufreq_offline_prepare/finish routines
  cpufreq: Call __cpufreq_governor() with policy->rwsem held
  cpufreq: Remove cpufreq_governor_lock
