Merge ACPICA changes, ACPI OS-layer changes, ACPI bus-type and _OSC support changes and ACPI tables parsing changes for 5.18-rc1: - Use uintptr_t and offsetof() in the ACPICA code to avoid compiler warnings regarding NULL pointer arithmetic (Rafael Wysocki). - Fix possible NULL pointer dereference in acpi_ns_walk_namespace() when passed "acpi=off" in the command line (Rafael Wysocki). - Fix and clean up acpi_os_read/write_port() (Rafael Wysocki). - Introduce acpi_bus_for_each_dev() and use it for walking all ACPI device objects in the Type C code (Rafael Wysocki). - Fix the _OSC platform capabilities negotioation and prevent CPPC from being used if the platform firmware indicates that it not supported via _OSC (Rafael Wysocki). - Add AGDI and CEDT to the list of known ACPI table signatures (Ilkka Koskinen, Robert Kiraly). * acpica: ACPICA: Avoid walking the ACPI Namespace if it is not there ACPICA: Use uintptr_t and offsetof() in Linux kernel builds * acpi-osl: ACPI: OSL: Fix and clean up acpi_os_read/write_port() * acpi-bus: ACPI: bus: Avoid using CPPC if not supported by firmware Revert "ACPI: Pass the same capabilities to the _OSC regardless of the query flag" ACPI: bus: Introduce acpi_bus_for_each_dev() * acpi-tables: ACPI: tables: Add AGDI to the list of known table signatures ACPI: tables: Add CEDT signature to the list of known tables
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.
