Steps to Reproduce
====================
1. Install Ubuntu 14.10 guest on PowerKVM.
2. Setup hugepage backing guest VM.
3. Try madv_poison.c code to test madvise sys. call with HWPOISON mode(test code is attached).
gcc -o madv_poison madv_poison.c
./madv_poison -C -i 1 (1 - shm_test)
Ubuntu 14.10 LE throws kernel bug :

The test code works fine with x86/Ubuntu VM so if it is not supported on power then it should have thrown an error not supported as it does with PowerKVM / RHEL 7 VM.
Intel/Ubuntu 14.04 VM: =================================> Working fine.
