Rafael J. Wysocki 3d031d0d8d Merge branch 'pm-cpuidle'
Fix an issue in the PSCI cpuidle driver introduced recently and a nasty
x86 power regression introduced in 6.15:

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

 - 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).

* pm-cpuidle:
  Revert "x86/smp: Eliminate mwait_play_dead_cpuid_hint()"
  cpuidle: psci: Fix uninitialized variable in dt_idle_state_present()

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.
