Hi Linus,

Please pull from the tag

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \

with top-most commit c3a74f8e25e97166ca0f954414825ae98a3209f6

Merge branch 'pm-cpufreq'

on top of commit b4ec805464a4a0299216a003278351d0b4806450

Merge tag 'pm-5.11-rc1' of

to receive more power management updates for 5.11-rc1.

These update the CPPC cpufreq driver and intel_pstate (which
involves updating the cpufreq core and the schedutil governor)
and make janitorial changes in the ACPI code handling processor


- Rework the passive-mode "fast switch" path in the intel_pstate
driver to allow it receive the minimum (required) and target
(desired) performance information from the schedutil governor so
as to avoid running some workloads too fast (Rafael Wysocki).

- Make the intel_pstate driver allow the policy max limit to be
increased after the guaranteed performance value for the given
CPU has increased (Rafael Wysocki).

- Clean up the handling of CPU coordination types in the CPPC
cpufreq driver and make it export frequency domains information
to user space via sysfs (Ionela Voinescu).

- Fix the ACPI code handling processor objects to use a correct
coordination type when it fails to map frequency domains and drop
a redundant CPU map initialization from it (Ionela Voinescu, Punit



Ionela Voinescu (5):
ACPI: processor: fix NONE coordination for domain mapping failure
cppc_cpufreq: use policy->cpu as driver of frequency setting
cppc_cpufreq: clarify support for coordination types
cppc_cpufreq: expose information on frequency domains
cppc_cpufreq: replace per-cpu data array with a list

Punit Agrawal (1):
ACPI: processor: Drop duplicate setting of shared_cpu_map

Rafael J. Wysocki (4):
cpufreq: schedutil: Add util to struct sg_cpu
cpufreq: Add special-purpose fast-switching callback for drivers
cpufreq: intel_pstate: Implement the ->adjust_perf() callback
cpufreq: intel_pstate: Use most recent guaranteed performance values
