Subject: mm/pgtable: make pte_next_pfn() independent of set_ptes()
Date: Mon, 29 Jan 2024 13:46:42 +0100
Let's provide pte_next_pfn(), independently of set_ptes(). This allows
for using the generic pte_next_pfn() version in some arch-specific
set_ptes() implementations, and prepares for reusing pte_next_pfn() in
other context.
