Linux 4.7-rc7

Power management fixes for v4.7-rc7

 - Fix a recent performance regression on Power systems (powernv
   and pseries) introduced by a core cpuidle commit that decreased
   the precision of the last_residency conversion from nano- to
   microseconds, which should not matter in theory, but turned out
   to play not-so-well with the special "snooze" idle state on Power
   (Shreyas B Prabhu).

 - Fix a crash during resume from hibernation on x86-64 caused by
   possible corruption of the kernel text part of page tables in the
   last phase of image restoration exposed by a security-related
   change during the 4.3 development cycle (Rafael Wysocki).

ACPI fixes for v4.7-rc7

 - Fix a lock ordering issue in ACPICA introduced by a recent commit
   that attempted to fix a deadlock in the dynamic table loading code
   which in turn appeared after changes related to the handling of
   module-level AML also made in this cycle (Lv Zheng).

 - Fix a recent regression in the ACPI IRQ management code that may
   cause PCI drivers to be unable to register an IRQ if that IRQ
   happens to be shared with a device on the ISA bus, like the
   parallel port, by reverting one commit entirely and restoring the
   previous behavior in two other places (Sinan Kaya).

 - Fix a recent regression in the ACPI AML debugger introduced by
   the commit that removed incorrect usage of IS_ERR_VALUE() from
   multiple places (Lv Zheng).

Linux 4.7-rc6

Power management fixes for v4.7-rc6

 - Fix a recent intel_pstate regression that caused the number of
   wakeups to increase significantly on an idle system in some cases
   due to excessive synchronize_sched() invocations (Rafael Wysocki).

 - Fix unnecessary invocations of WARN_ON() in the cpufreq core
   after cpufreq has been suspended introduced during the 4.6 cycla
   (Rafael Wysocki).

 - Fix an error code path in the cpufreq-dt-platdev driver that
   forgets to drop a reference to a DT node (Masahiro Yamada).

ACPI fix for v4.7-rc6

Fix an expression in the ACPI PCI IRQ management code added by a
recent commit that overlooked missing parens in it, so the result
of the computation is incorrect in some cases (Sinan Kaya).

Linux 4.7-rc5

Power management fixes for v4.7-rc5

 - Fix a latent initialization issue in the pcc-cpufreq driver
   (incorrect initial value of a structure field) that has been
   uncovered by a recent ACPICA commit (Mike Galbraith).

 - Add a missing notification in an update_devfreq() error code
   path forgotten by a recent devfreq commit (Chanwoo Choi).

 - Fix devfreq device frequency initialization (Lukasz Luba).

 - Fix an incorrect IS_ERR() check in the devfreq framework
   discovered by the Smatch checker (Dan Carpenter).

 - Drop two excessive put_device() calls from the devfreq framework
   (MyungJoo Ham, Cai Zhiyong).

 - Fix a possible memory leak in the devfreq framework and drop an
   unnecessary kfree() invocation from it (MyungJoo Ham).
