[PATCH v8 05/15] mm: convert PTE table entry to pte

[Alexander Gordeev]

From: Muhammad Usama Anjum <usama.anjum@xxxxxxx>

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().
