Linus Torvalds 976aa630da More power management updates for 6.16-rc1
- 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).

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:

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
