     enabling

   - CXL documentation typo and clarity fixes

   - Make cxl_bus_type constant

   - Introduce new helper cxl_resource_contains_addr() to check address
     availability

   - Fix wrong DPA checking for PPR operation

   - Remove core/acpi.c and CXL core dependency on ACPI

   - Introduce ACQUIRE() and ACQUIRE_ERR() for conditional locks

   - Add CXL updates utilizing ACQUIRE() macro to remove gotos and
     improve readability

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.
