I notice that the mem_map in these logs have overlapping ranges, which results
in unnecessary work when creating the PTs. For this reason, it would

I'm sorry to bother you, but have you had a chance to look at the log
I shared with you?

The problem happens so early that I am not able to narrow it down at
subsystem level.

In the add_map() function, for each level it populates, it iterates from
the root of the PT tree, making it ineficient if a mapping needs to occur
past level 1.
Instead, replace it with a recursive (and much simpler) algorithm
that keeps the complexity as low as possible.
