Joerg Roedel 161b28aae1 iommu/vt-d: Make sure IOMMUs are off when intel_iommu=off
When booting into a kexec kernel with intel_iommu=off, and
the previous kernel had intel_iommu=on, the IOMMU hardware
is still enabled and gets not disabled by the new kernel.

This causes the boot to fail because DMA is blocked by the
hardware. Disable the IOMMUs when we find it enabled in the
kexec kernel and boot with intel_iommu=off.

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.
