Joerg Roedel 89736a0ee8 Revert "iommu/amd: Remove the leftover of bypass support"
This reverts commit 7a5dbf3ab2.

This commit not only removes the leftovers of bypass
support, it also mostly removes the checking of the return
value of the get_domain() function. This can lead to silent
data corruption bugs when a device is not attached to its
dma_ops domain and a DMA-API function is called for that
device.

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.
