The purpose of this patch is to remove 128 bytes buffer limitation imposed in bios_args structure. A limiting factor discovered during this investigation was the struct bios_args.data size restriction. The data member size limits all possible WMI commands to those requiring buffer size of 128 bytes or less. Several WMI commands and queries require a buffer size larger than 128 bytes hence limiting current and feature supported by the driver. It is for this reason, struct bios_args.data changed and is dynamically allocated. hp_wmi_perform_query function changed to handle the memory allocation and release of any required buffer size. All changes were validated on a HP ZBook Workstation notebook, HP EliteBook x360, and HP EliteBook 850 G8. Additional validation was included in the test process to ensure no other commands were incorrectly handled.

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.
