Hi Linus,
Please pull from the tag

pm-6.16-rc2
with top-most commit dd3581853c5f190c3a7bd1de78f5ecb2905a77a7
Merge branch 'pm-cpuidle'
on top of commit 19272b37aa4f83ca52bdf9c16d5d81bdd1354494
Linux 6.16-rc1
to receive power management updates for 6.16-rc2.
These fix the cpupower utility installation, fix up the recently added
Rust abstractions for cpufreq and OPP, restore the x86 update
eliminating mwait_play_dead_cpuid_hint() that has been reverted during
the 6.16 merge
window along with preventing the failure caused by it from happening, and
clean up mwait_idle_with_hints() usage in intel_idle:
- Implement CpuId Rust abstraction and use it to fix doctest failure
related to the recently introduced cpumask abstraction (Viresh Kumar).
- Do minor cleanups in the `# Safety` sections for cpufreq abstractions
added recently (Viresh Kumar).
- Unbreak cpupower systemd service units installation on some systems
by adding a unitdir variable for specifying the location to install
them (Francesco Poli).
- Eliminate mwait_play_dead_cpuid_hint() again after reverting its
elimination during the 6.16 merge window due to a problem with
handling "dead" SMT siblings, but this time prevent leaving them in
C1 after initialization by taking them online and back offline when
a proper cpuidle driver for the platform has been registered (Rafael
Wysocki).
- Update data types of variables passed as arguments to
mwait_idle_with_hints() to match the function definition
after recent changes (Uros Bizjak).
Thanks!
