01c8f1c44b83a0825b573e7c723b033cece37b86 is the first bad commit
commit 01c8f1c44b83a0825b573e7c723b033cece37b86
Author: Dan Williams <dan.j.williams@xxxxxxxxx>

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.
