Thomas Zimmermann b1def7fadf drm/ast: Init iosys_map pointer as I/O memory for damage handling
Ast hardware scans out the primary plane from video memory, which
is in I/O-memory space. Hence init the damage handler's iosys_map
pointer as I/O memory.

Not all platforms support accessing I/O memory as system memory,
although it's usually not a problem in ast's x86-based systems.

The error report is at [1].

README

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.
