Arnd Bergmann a8e9f5f672 Enable async communication with tee supplicant
This pull request enables asynchronous communication with TEE supplicant
 by introducing meta parameters in the user space API. The meta
 parameters can be used to tag requests with an id that can be matched
 against an asynchronous response as is done here in the OP-TEE driver.
 
 Asynchronous supplicant communication is needed by OP-TEE to implement
 GlobalPlatforms TEE Sockets API Specification v1.0.1. The specification
 is available at https://www.globalplatform.org/specificationsdevice.asp.
 
 This change is backwards compatible allowing older supplicants to work
 with newer kernels and vice versa.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
