ACPICA commit bc02c76d518135531483dfc276ed28b7ee632ce1 The current ACPI_ACCESS_*_WIDTH defines do not provide a way to test that size is small enough to not cause an overflow when applied to a 32-bit integer. Rather than adding more magic numbers, add ACPI_ACCESS_*_SHIFT, ACPI_ACCESS_*_MAX, and ACPI_ACCESS_*_DEFAULT #defines and redefine ACPI_ACCESS_*_WIDTH in terms of the new #defines. This was inititally reported on Linux where a size of 102 in ACPI_ACCESS_BIT_WIDTH caused an overflow error in the SPCR initialization code.

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.
