     net/mm: use PGTY for tracking page pool pages

     Currently, we use page->pp_magic to determine whether a page belongs to
     a page pool. It's not ideal as the field is aliased with other page
     types, and thus needs to to rely on elaborated rules to work. Add a new
     page type for page pool.

Hi Pavel,

I need this work to be done to remove ->pp_magic in struct page.  Will
you let me work on this work?  Or can you please refine and post this

No response I got.  Thus, I started.  I hope you understand.

Missed the first message and then got busy. Anyway, sure, go ahead.
