    Pull libata updates from Tejun Heo:
    
     - Adam added opt-in ATA command priority support.
    
     - There are machines which hide multiple nvme devices behind an ahci
       BAR. Dan Williams proposed a solution to force-switch the mode but
       deemed too hackishd. People are gonna discuss the proper way to
       handle the situation in nvme standard meetings. For now, detect and
       warn about the situation.
    
     - Low level driver specific changes.
    
    Christoph Hellwig pipes in about the hidden nvme warning:
     "I wish that was the case. We've pretty much agreed that we'll want to
      implement it as a virtual PCIe root bridge, similar to Intels other
      'innovation' VMD that we work around that way.
    
      But Intel management has apparently decided that they don't want to
      spend more cycles on this now that Lenovo has an optional BIOS that
      doesn't force this broken mode anymore, and no one outside of Intel
      has enough information to implement something like this.
    
      So for now I guess this warning is it, until Intel reconsideres and
      spends resources on fixing up the damage their Chipset people caused"
