Greg Kroah-Hartman 08bd511fe9 PCI/ATS: Restore EXPORT_SYMBOL_GPL() for pci_{enable,disable}_ats() 
[ Upstream commit bb950bca5d ]

Commit d355bb2097 ("PCI/ATS: Remove unnecessary EXPORT_SYMBOL_GPL()")
unexported a bunch of symbols from the PCI core since the only external
users were non-modular IOMMU drivers. Although most of those symbols
can remain private for now, 'pci_{enable,disable_ats()' is required for
the ARM SMMUv3 driver to build as a module, otherwise we get a build
failure as follows:

  | ERROR: "pci_enable_ats" [drivers/iommu/arm-smmu-v3.ko] undefined!
  | ERROR: "pci_disable_ats" [drivers/iommu/arm-smmu-v3.ko] undefined!

Re-export these two functions so that the ARM SMMUv3 driver can be build
as a module.

README 

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 Restructured Text 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.
