Linux v4.13-rc3

to receive power management fixes for v4.13-rc4.

These fix two cpufreq issues, one introduced recently and one
related to recent changes, fix cpufreq documentation, fix up
recently added code in the Thunderbolt driver and update runtime
PM framework documentation.


- Fix the handling of the scaling_cur_freq cpufreq policy attribute
on x86 systems with the MPERF/APERF registers present to make it
behave more as expected after recent changes (Rafael Wysocki).

- Drop a leftover callback from the intel_pstate driver which also
prevents the cpuinfo_cur_freq cpufreq policy attribute from being
incorrectly exposed when intel_pstate works in the active mode
(Rafael Wysocki).

- Add a missing piece describing the cpuinfo_cur_freq policy
attribute to cpufreq documentation (Rafael Wysocki).

- Fix up a recently added part of the Thunderbolt driver to avoid
aborting system suspends if its mailbox commands time out (Rafael

- Update device runtime PM framework documentation to reflect the
current behavior of the code (Johan Hovold).
