- Fix an issue in the PCI handling of the "thaw" transition during
hibernation (after creating an image), introduced by a bug fix
from the 4.13 cycle and exposed by recent changes in the IRQ
subsystem, that caused pci_restore_state() to be called for
devices in low-power states in some cases which is incorrect
and breaks MSI management on some systems (Rafael Wysocki).
- Fix a recent regression in the imx6q cpufreq driver that broke
speed grading on i.MX6 QuadPlus by omitting checks causing
invalid operating performance points (OPPs) to be disabled on
that SoC as appropriate (Lucas Stach).
- Fix a regression introduced during the 4.14 cycle in the ondemand
and conservative cpufreq governors that causes the sampling
interval used by them to be shorter than the tick period in some
cases which leads to incorrect decisions (Rafael Wysocki).

Pull power management fixes from Rafael Wysocki:
"These fix a regression in the ondemand and conservative cpufreq
governors that was introduced during the 4.13 cycle, a recent
regression in the imx6q cpufreq driver and a regression in the PCI
handling of hibernation from the 4.14 cycle.
Specifics:
- Fix an issue in the PCI handling of the "thaw" transition during
hibernation (after creating an image), introduced by a bug fix from
