commita7583e72a5upstream. The commit0f27cff859("ACPI: sysfs: Make ACPI GPE mask kernel parameter cover all GPEs") says: "Use a bitmap of size 0xFF instead of a u64 for the GPE mask so 256 GPEs can be masked" But the masking of GPE 0xFF it not supported and the check condition "gpe > ACPI_MASKABLE_GPE_MAX" is not valid because the type of gpe is u8. So modify the macro ACPI_MASKABLE_GPE_MAX to 0x100, and drop the "gpe > ACPI_MASKABLE_GPE_MAX" check. In addition, update the docs "Format" for acpi_mask_gpe parameter.

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.
