The patches were backported from stable 4.4 to Oracle UEK4.1, and from UEK4.1 to Stable 4.1
You'd want to consider also taking trampoline stack entry patches we currently are putting into SLE12-SP[23] kernel tree [1], which also bases on the original Hugh's 4.4 port.
I've notified Greg already that trampoline stack entry should be put into 4.4-stable proper as well, but that hasn't happened yet.
[1] you can find those on https://kernel.suse.com/; the patches that are currently in (commits 6d3ee9dc14bafff and f7de61af517916 in kernel-source.git there) do pass the usual battery of PTI testing. There will be some changes made to it to avoid external module ABI breakage, but those will not be picked up by stable I guess, and you probably don't care either.
