[Rafael J. Wysocki]

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.15-rc2

with top-most commit cdef1196608892b9a46caa5f2b64095a7f0be60c

 cpufreq: schedutil: Destroy mutex before kobject_put() frees the memory

on top of commit 6880fa6c56601bb8ed59df6c30fd390cc5f6dd8f

 Linux 5.15-rc1

to receive power management fixes for 5.15-rc2.

These fix two cpufreq issues, one in the intel_pstate driver and one
in the core.

Specifics:

 - Prevent intel_pstate from avoiding to use HWP, even if instructed
   to do so via the kernel command line, when HWP has been enabled
   already by the platform firmware (Doug Smythies).

 - Prevent use-after-free from occurring in the schedutil cpufreq
   governor on exit by fixing a core helper function that attempts
   to access memory associated with a kobject after calling
   kobject_put() on it (James Morse).

Thanks!
