Vineet Gupta d5272aaa82 ARC: mm: fix new code about cache aliasing
Manual/partial revert of 8690bbcf3b ("Introduce cpu_dcache_is_aliasing() across all architectures")

Current generation of ARCv2/ARCv3 based HSxx cores are only PIPT (to software
at least).

Legacy ARC700 cpus could be VIPT aliasing (based on cache geometry and
PAGE_SIZE) [1] however recently that support was ripped out so VIPT aliasing
cache is not relevant to ARC anymore.

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 reStructuredText 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.
