Hi Linus,

Please pull from the tag

with top-most commit d5f8e5f6040d052d44fcbf4f31dd35145c0c8d7d

 cpufreq: powernow-k8: Fix possible memory leak in powernowk8_cpu_init()

on top of commit 1590cf0329716306e948a8fc29f1d3ee87d3989f

 Linux 7.2-rc4

to receive power management fixes for 7.2-rc6.

These fix issues related to cpufreq, in the ACPI CPPC library and the
generic CPPC cpufreq driver, in the powernow-k8 and amd-pstate drivers,
and in the schedutil governor:

 - Allow fast frequency switching in the ACPI CPPC library only when
   every supported control used by the driver callback has an address
   space already accepted for fast access (Christian Loehle)

 - Skip writes to unsupported performance controls in the ACPI CPPC
   library (Christian Loehle)

 - Update cppc_cpufreq_update_perf_limits() to read policy->min and
   policy->max once and, if the lockless snapshot is inconsistent,
   reduce the minimum to the observed maximum, along the lines of
   cpufreq_driver_resolve_freq() (Christian Loehle)

 - Fix a possible memory leak in the powernowk8_cpu_init() error
   paths (Abdun Nihaal)

 - Loosen the requirement on lowest nonlinear frequency != min freq in
   the amd-pstate driver that is too tight for new systems some of
   which actually have the lowest nonlinear frequency identical to the
   minimum frequency (Mario Limonciello)

 - Prevent amd-pstate from loading on unsupported hardware (Rong Zhang)

 - Address an initialization race in the schedutil governor when it
   runs on multi-CPU cpufreq policies, by making it initialize all
   per-CPU structures first and only then publish the per-CPU
   utilization update hooks (Zhongqiu Han)

Thanks!
