Vivek Gautam b48522b788 iommu/arm-smmu: Error out only if not enough context interrupts 
commit d1e20222d5 upstream.

Currently we check if the number of context banks is not equal to
num_context_interrupts. However, there are booloaders such as, one
on sdm845 that reserves few context banks and thus kernel views
less than the total available context banks.
So, although the hardware definition in device tree would mention
the correct number of context interrupts, this number can be
greater than the number of context banks visible to smmu in kernel.
We should therefore error out only when the number of context banks
is greater than the available number of context interrupts.

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.
