Merge tag 'pm-6.16-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull more power management updates from Rafael Wysocki:
 "These revert an x86 commit that introduced a nasty power regression on
  some systems, fix PSCI cpuidle driver and ACPI cpufreq driver
  regressions, add Rust abstractions for cpufreq, OPP, clk, and
  cpumasks, add a Rust-based cpufreq-dt driver, and do a minor SCMI
  cpufreq driver cleanup:

   - Revert an x86 commit that went into 6.15 and caused idle power,
     including power in suspend-to-idle, to rise rather dramatically on
     systems booting with "nosmt" in the kernel command line (Rafael
     Wysocki)

   - Prevent freeing an uninitialized pointer in error path of
     dt_idle_state_present() in the PSCI cpuidle driver (Dan Carpenter)

   - Use KHz as the nominal_freq units in get_max_boost_ratio() in the
     ACPI cpufreq driver (iGautham Shenoy)

   - Add Rust abstractions for CPUFreq framework (Viresh Kumar)

   - Add Rust abstractions for OPP framework (Viresh Kumar)

   - Add basic Rust abstractions for Clk and Cpumask frameworks (Viresh
     Kumar)

   - Clean up the SCMI cpufreq driver somewhat (Mike Tipton)"
