Diag 308 subcodes expect a physical address as their parameter. This currently is not a bug, but in the future physical and virtual addresses might differ. Fix the confusion by doing a virtual-to-physical conversion in the exported diag308() and leave the assembly wrapper __diag308() alone. Note that several callers pass NULL as addr, so check for the case when NULL is passed and pass 0 to hardware since virt_to_phys(0) might be nonzero.

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.
