From 379c926d6334427b35fe7747f7758c865e20e9a9 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Thu, 15 Oct 2020 20:04:29 -0700 Subject: powerpc/mm: move setting pte specific flags to pfn_pte powerpc used to set the pte specific flags in set_pte_at(). This is different from other architectures. To be consistent with other architecture update pfn_pte to set _PAGE_PTE on ppc64. Also, drop now unused pte_mkpte. We add a VM_WARN_ON() to catch the usage of calling set_pte_at() without setting _PAGE_PTE bit. We will remove that after a few releases. With respect to huge pmd entries, pmd_mkhuge() takes care of adding the _PAGE_PTE bit.
