- Address a load balancer regression by making the load balancer use the
same logic as the wakeup path to spread tasks in the LLC domain.
- Prefer the CPU on which a task run last over the local CPU in the fast
wakeup path for asymmetric CPU capacity systems to align with the
symmetric case. This ensures more locality and prevents massive
migration overhead on those asymetric systems
- Fix a memory corruption bug in the scheduler debug code caused by
handing a modified buffer pointer to kfree().

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 Restructured Text 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.
