The detail of transparent hugepage are hidden by design. We hope it
keep 'transparent'.
Until any explain why we should expose KPF_THP, we don't agree it.

The reason why I want to know physical address of thp is testing.
I'm working on memory error recovery and writing test code to confirm
that memory recovery really works when an error occurs on thps.
There I need to locate thps on the physical memory.

I'm sorry, I simply don't understand what you say. Why do you think
memory recovery and thp are related feature?

This is because memory error can occur on thp and then we should be
able to handle them (otherwise we can use corrupted date) and
verify that it works.
