Thanks for replying!

we have not compared with uksm yet. 

The benefit is that adding more CPU cores can linearly boost speed as far as we tested. It also allows any CPU to donate spare time for the job.

The qemu patch is used for another feather named PPR(Per Page Recycler). PageONE does not need that qemu patch.
