====================================================================================================================== 01c8f1c44b83a0825b573e7c723b033cece37b86 is the first bad commit commit 01c8f1c44b83a0825b573e7c723b033cece37b86 Author: Dan Williams dan.j.williams@intel.com Date: Fri Jan 15 16:56:40 2016 -0800

 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.
