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.

Hmm, this commit could only cause a behavior change if it modifies the
value of the pfn as seen by insert_pfn().  Can you try the attached
debug patch to see if that assumption is being violated?
Had to manually delete the lines in the second part of the patch.
