From 7106c51ee9a1b65eff63496636fce36bf246c1a0 Mon Sep 17 00:00:00 2001 From: Mike Rapoport Date: Fri, 4 Feb 2022 13:49:20 -0500 Subject: arch: Add pmd_pfn() where it is missing We need to use this function in common code, so define it for architectures and/or configrations that miss it. The result of pmd_pfn() will only be used if TRANSPARENT_HUGEPAGE is enabled, but a function or macro called pmd_pfn() must be defined, even on machines with two level page tables.
