on top of commit 07d9a380680d1c0eb51ef87ff2eab5c994949e69

 Linux 4.9-rc2

to receive power management fixes for v4.9-rc3.

These fix two intel_pstate issues related to the way it works when
the scaling_governor sysfs attribute is set to "performance" and
fix up messages in the system suspend core code.

Specifics:

 - Fix a missing KERN_CONT in a system suspend message by converting
   the affected code to using pr_info() and pr_cont() instead of the
   "raw" printk() (Jon Hunter).

 - Make intel_pstate set the CPU P-state from its .set_policy()
   callback when the scaling_governor sysfs attribute is set to
   "performance" so that it interacts with NOHZ_FULL more
   predictably which was the case before 4.7 (Rafael Wysocki).

 - Make intel_pstate always request the maximum allowed P-state when
   the scaling_governor sysfs attribute is set to "performance" to
   prevent it from effectively ingoring that setting is some
   situations (Rafael Wysocki).

Thanks!
