commit3337a6fea2upstream. Per the "SMC calling convention specification", the 64-bit calling convention can only be used when the client is 64-bit. Whereas the 32-bit calling convention can be used by either a 32-bit or a 64-bit client. Currently during SCM probe, irrespective of the client, 64-bit calling convention is made, which is incorrect and may lead to the undefined behaviour when the client is 32-bit. Let's fix it.

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.
