From 01c8f1c44b83a0825b573e7c723b033cece37b86 Mon Sep 17 00:00:00 2001 From: Dan Williams Date: Fri, 15 Jan 2016 16:56:40 -0800 Subject: mm, dax, gpu: convert vm_insert_mixed to pfn_t Convert the raw unsigned long 'pfn' argument to pfn_t for the purpose of evaluating the PFN_MAP and PFN_DEV flags. When both are set it triggers _PAGE_DEVMAP to be set in the resulting pte. There are no functional changes to the gpu drivers as a result of this conversion.
