It was not taking 150s for me but some tests were taking around 7-8 
secs. I realized that call to igt_get_fb_tile_size() was happening 
inside a busy loop.
I have fixed the issue and I see most of the tests completing within a 
sec now. I have floated the updated patch and here is the link to new 
series. Plz review.
