[PATCH v2 5/8] mm: convert PTE table entry to pte

[Muhammad Usama Anjum]

The non-MMU stub receives hw_pte_t but returns a software PTE value. It
has no attached PTE that requires ptep_get(), so convert only the stored
entry through __pte_from_hw().

Changes since v1:
- Explain why the NOMMU stub does not use ptep_get().
- Use software PTE value terminology.
