Joerg Roedel a33bf8d8ce iommu: Restore iommu_flush_iotlb_all()
This patch restores the iommu_flush_iotlb_all() function.
Commit

	69e5a17511 ("iommu: Remove useless flush from iommu_create_device_direct_mappings()")

claims it removed the last call-site, except it did not. There is still
at least one caller in

	drivers/gpu/drm/msm/msm_iommu.c

so keep the function around until all call-sites are updated.

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.
