Steps:
------
1. Execute IGT tests:
# ./gem_mmap_gtt --r big-bo-tiledX
# ./gem_mmap_gtt --r big-bo-tiledY
# ./gem_mmap_gtt --r big-copy-XY
# ./gem_mmap_gtt --r huge-bo-tiledX
# ./gem_mmap_gtt --r huge-bo-tiledY
# ./gem_mmap_gtt --r huge-copy-XY

Actual results:
---------------
Test result is CRASH

Expected result:
----------------
Tests are Pass
