No, don't do another version. Jason is right, this approach is wrong.
The point of SVA is that it doesn't require the application to do
anything special. If jitter from too-frequent page migration is actually
a problem, then fix the frequency of page migration. Don't pretend that
this particular application is so important that it prevents the kernel
from doing its housekeeping.
