Drop GPL from of_node_to_nid() export to match other arches

[bugproxy]

== SRU Justification ==
The commit requested in this bug exposes functionality needed by the Nvidia device driver on POWER9.

This patch is a clean cherry pick and specific to powerpc.

This commit is in mainline as of 4.11-rc1.

We need to backport mainline commit be9ba9ff93cc ("Drop GPL from of_node_to_nid() export to match other arches") to the Ubuntu 4.10 kernel.

This exposes functionality needed by the Nvidia device driver on POWER9.

Ping! Could someone have a look at this?

[Andrew Cloke (andrew-cloke)]

Apologies for the delay. This bug somehow missed our initial handling process. I've now assigned to the kernel team.

[Joseph Salisbury (jsalisbury)]

I built a Zesty test kernel with a pick of commit be9ba9ff93cc. The test kernel can be downloaded from:

http://kernel.ubuntu.com/~jsalisbury/lp1709179

Can you test this kernel and see if it resolves this bug?

Thanks in advance!

Hi Canonical, any news on this bug? This is special for us, because of some out-of-the-three modules we need to use internally.

[Joseph Salisbury (jsalisbury)]

An SRU request was submitted for this bug, and the fix should be included in the next set up updates:

Hi,

I understand that people also need this patch for 16.04.3's 4.10 kernel, that is, in the linux-hwe kernel.
Joseph, will that fix in Zesty's kernel be automatically propagated to Xenial's linux-hwe or do we
need any other action for this ?
Thanks!

F.

Marking the development task fix released as this patch was merged in 4.11, and artful is already using 4.12.

Patches to the zesty kernel are automatically propagated into the hwe kernel.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-zesty' to 'verification-done-zesty'. If the problem still exists, change the tag 'verification-needed-zesty' to 'verification-failed-zesty'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

I verified that linux-image-4.10.0-36-generic/zesty-proposed has this fix.
