Bug detailed description:
-------------------------
   On ILK platform ,running gem_tiled_fence_blits of the
Intel-gpu-tools will fail.

  the error on the console is like this:
  not enough RAM to run test, reducing buffer count
  Using 1631 1MiB buffers
  Expected 0x0d4c0000, found 0x15980000 at offset 0x00000000
  Aborted (core dumped)

   Here is the GDB backtrace:
#0  0x00000037f7034085 in raise () from /lib64/libc.so.6
#1  0x00000037f7035a36 in abort () from /lib64/libc.so.6
#2  0x0000000000401854 in check_bo (argc=<value optimized out>, argv=<value optimized out>) at gem_tiled_fence_blits.c:98
#3  main (argc=<value optimized out>, argv=<value optimized out>) at gem_tiled_fence_blits.c:162

   Here is a good kernel commit:

   If have a demand,I can bisect it.
