The page allocation performance requirements of different workloads
are usually different.  So, we need to tune the PCP (Per-CPU Pageset)
high on each CPU automatically to optimize the page allocation
performance.

In this patchset, a PCP high auto-tuning mechanism is implemented.
The description of the algorithm and the test results can be found in
the patch description of [2/2].

Best Regards,
Huang, Ying
