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.
