The system got HUGETLB enabled in the config:
$ cat /boot/config-4.13.0-16-generic | grep HUGETLB
CONFIG_CGROUP_HUGETLB=y
CONFIG_HUGETLBFS=y
CONFIG_HUGETLB_PAGE=y
But there is no hugepage_size in meminfo:
$ cat /proc/meminfo | grep Hugepagesize
Looks like hugepage is not supported. I will fix the detection part in
our test suite.
Not sure if this is an expected behaviour in the kernel.
