What do you want to solve, as yamt asked you first?

He said pmap_extract() could be used to get PA from VA.
You just answered pmap_extract() was bad API.
What you were trying to solve?

If existing API can solve it without bad side effect,
I don't think it's so bad for your purpose and
its design should be another discussion.
