[SRU][Zesty][PATCH 0/2] Fixes for LP:1715073

[Joseph Salisbury]

BugLink: http://bugs.launchpad.net/bugs/1715073

== SRU Justification ==
IBM reports that When doing SRIOV if they unload VFs they will see a warning
that is coming from the fix for bugzilla: Bug 146479 (LP1625318).

Commit 5b0948dfe is a prereq commit for Zesty, but not for Artful, since that commit 
was included in mainline as of 4.11-rc1.

Commit 0fc690a7c3f is not in mainline as of yet, and was a clean pick from linux-next.
Commit 0fc690a7c3f is also need in Artful, but will be SRU'd seperatly, since Z needs
 a prereq commit.

== Fixes ==

    PCI: Lock each enable/disable num_vfs operation in sysfs

    PCI: Disable VF decoding before pcibios_sriov_disable() updates resources



== Regression Potential ==
The primary patch is only adding a call to pcibios_sriov_disable(), which 
disables VF memory decoding before calling pcibios_sriov_disable().  No other major
changes are made.

== Test Case ==
A test kernel was built with these patches and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
