Robin Murphy 1cf9e54e91 iommu/arm-smmu-v3: Clean up address masking
Before trying to add the SMMUv3.1 support for 52-bit addresses, make
things bearable by cleaning up the various address mask definitions to
use GENMASK_ULL() consistently. The fact that doing so reveals (and
fixes) a latent off-by-one in Q_BASE_ADDR_MASK only goes to show what a
jolly good idea it is...

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.
