Yunfeng Ye 5850179285 ACPI: sysfs: Change ACPI_MASKABLE_GPE_MAX to 0x100
commit a7583e72a5f22470d3e6fd3b6ba912892242339f upstream.

The commit 0f27cff859 ("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.

README

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.
