Okay! Could you check following git tree and branch to fix the
reported regression?

https://github.com/JoonsooKim/linux.git cma-fixup-thp-next-20180403

Related commits are:
f11152b mm/thp: don't count ZONE_MOVABLE as the target for freepage reserving
b2adb03 Revert "Revert "mm/cma: manage the memory of the CMA area by
using the ZONE_MOVABLE""
76148e2 Revert "Revert "mm/page_alloc: don't reserve ZONE_HIGHMEM for
ZONE_MOVABLE request""

Base commit is '76148e2' and this regression happens on 'b2adb03'.
Fix is commit 'f11152b'.

Thanks.
