Sricharan R e19898077c iommu/arm-smmu: Set privileged attribute to 'default' instead of 'unprivileged'
Currently the driver sets all the device transactions privileges
to UNPRIVILEGED, but there are cases where the iommu masters wants
to isolate privileged supervisor and unprivileged user.
So don't override the privileged setting to unprivileged, instead
set it to default as incoming and let it be controlled by the pagetable
settings.

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.
