From f25748e3c34eb8bb54853e9adba2d3dcf030503c Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Fri, 15 Jan 2016 16:56:43 -0800 Subject: mm, dax: convert vmf_insert_pfn_pmd() to pfn_t Similar to the conversion of vm_insert_mixed() use pfn_t in the vmf_insert_pfn_pmd() to tag the resulting pte with _PAGE_DEVICE when the pfn is backed by a devm_memremap_pages() mapping.
