Subject: [GIT PULL] More power management updates for v5.11-rc1

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.11-rc1-2

with top-most commit c3a74f8e25e97166ca0f954414825ae98a3209f6

 Merge branch 'pm-cpufreq'

on top of commit b4ec805464a4a0299216a003278351d0b4806450

 Merge tag 'pm-5.11-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

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
objects.

Specifics:

 - 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
   Agrawal).

Thanks!

      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
