  According to the results of performance testing.
  We can get some important conlusion.

  Compare 2.5.51 with our FITH with pure kernel(2.5.51)
  The over head is as follow:

  Mmap Latency            about  17.8%
  Prot Fault                     about  63.5%
  Page Fault                    about 50%
