Bug Description

Steps:
1. Deploy an ARM64 system with Trusty
2. Install necessary packages
3. git clone --depth=1 -b next https://github.com/libhugetlbfs/libhugetlbfs.git
4. make BUILDTYPE=NATIVEONLY
5. execute the run_test.py in tests directory

Results:
 * you will see it stuck at shmoverride_linked test, no output for this test in syslog

truncate_reserve_wraparound (2M: 64): PASS
truncate_sigbus_versus_oom (2M: 64): PASS
get_huge_pages (2M: 64): PASS
shmoverride_linked (2M: 64):

This issue can be reproduced in 3.13.0-137 and 3.13.0-138 in proposed.
As we didn't run any regression-test on this node between 3.13.0-135 ~ 3.13.0-136 (this node was broken).

This test cannot be built on ARM64 before (till 3.13.0-133, we have changed to use the upstream repo since then) therefore I think this can be considered as not a regression.

With the libhugetlbfs updated recently, this will need to be revisited.
