mm/huge_memory: move more common code into insert_pmd()

Patch series "mm: vm_normal_page*() improvements", v3.

Cleanup and unify vm_normal_page_*() handling, also marking the huge
zerofolio as special in the PMD.  Add+use vm_normal_page_pud() and cleanup
that XEN vm_ops->find_special_page thingy.

There are plans of using vm_normal_page_*() more widely soon.


This patch (of 11):

Let's clean it all further up.

No functional change intended.
