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.
