Add the FWCTL_RPC ioctl which allows a request/response RPC call to device firmware. Drivers implementing this call must follow the security guidelines under Documentation/userspace-api/fwctl.rst The core code provides some memory management helpers to get the messages copied from and back to userspace. The driver is responsible for allocating the output message memory and delivering the message to the device.

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 reStructuredText 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.
