Hi Linus,
Please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \ pm+acpi-4.2-rc5
to receive power management and ACPI fixes for v4.2-rc5 with top-most commit d29809b8eb12d291d7b507fdaaa5e44707641685
Merge branches 'pm-cpufreq' and 'acpi-pm'
on top of commit cbfe8fa6cd672011c755c3cd85c9ffd4e2d10a6f
Linux 4.2-rc4
These fix three regressions, two recent ones (cpufreq core and ACPI device power management) and one introduced during the 4.1 cycle (intel_pstate).
Specifics:
- Fix a recently introduced issue in the cpufreq core causing it to attempt to create duplicate symbolic links to the policy directory in sysfs for CPUs that are offline when the cpufreq driver is being registered (Rafael J Wysocki).
- Fix a recently introduced problem in the ACPI device power management core code causing it to store an incorrect value in the device object's power.state field in some cases which in turn leads to attempts to turn power resources off while they should still be on going forward (Mika Westerberg).
- Fix an intel_pstate driver issue introduced during the 4.1 cycle which leads to kernel panics on boot on Knights Landing chips due to incomplete support for them in that driver (Lukasz Anaczkowski).
Thanks!
---------------
Lukasz Anaczkowski (1): intel_pstate: Add get_scaling cpu_defaults param to Knights Landing
Mika Westerberg (1): ACPI / PM: Use target_state to set the device power state
Rafael J. Wysocki (1): cpufreq: Avoid attempts to create duplicate symbolic links
