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

Result:
* The chunk-overcommit test case will fail

chunk-overcommit (2M: 64): Starting testcase "chunk-overcommit", pid 17370
overcommit: 31935 hugepages available: chunk1=15968 chunk2=15968
Looks like we've overcommitted, testing...
FAIL Killed by signal "Bus error" due to overcommit

Error message could be found in syslog:
AutotestCrashHandler: Application chunk-overcommi, PID 2269 crashed
AutotestCrashHandler: Writing core files to ['/home/ubuntu/autotest/client/results/default/libhugetlbfs/debug/crash.chunk-overcommi.2269']
