Hello Greg,
Could you please consider backporting to v4.4 the following commit:
commit b5b5b6fe643391209b08528bef410e0cf299b826
Author: Simon Guo <wei.guo.simon@gmail.com>
Date: Fri Oct 7 20:59:40 2016
mm: mlock: avoid increase mm->locked_vm on mlock() when already
mlock2(,MLOCK_ONFAULT)
It seems to be a trivial fix for:
https://bugs.linaro.org/show_bug.cgi?id=4043
(mlock203.c LTP test failing on v4.4)
Thanks in advance,

Where did you get that git commit id?
It's b155b4fde5bdde9fed439cd1f5ea07173df2ed31 in Linus's tree.
Something went really odd on your side here :(
