It's fixed by
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit/?h=linux-4.9.y&id=83946c33b9b99b5bc6157cfbf3970265f006c2bf

Thanks, will send in a new patch.
Stijn
It turns out this patch already made it into 4.4.116 as well:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit/?h=linux-4.4.y&id=4f3e6ab44b928ef70b77aa374886cb59fd9e4171
So please toss this patch. Evidently the X86_VSYSCALL_EMULATION bit
didn't interfere with the patch, so 4.4.116 still compiled fine at
first just like 4.4.115 and 4.4.114...
