Stefano Stabellini 9891f68160 CONFIG_XEN_PV breaks xen_create_contiguous_region on ARM
commit f900557170 upstream.

xen_create_contiguous_region has now only an implementation if
CONFIG_XEN_PV is defined. However, on ARM we never set CONFIG_XEN_PV but
we do have an implementation of xen_create_contiguous_region which is
required for swiotlb-xen to work correctly (although it just sets
*dma_handle).

[backport: remove change to xen_remap_pfn]

Cc: <stable@vger.kernel.org> # 4.12
Fixes: 1662439081 ("xen: create xen_create/destroy_contiguous_region() stubs for PVHVM only builds")

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.
