      Pull SCSI fix from James Bottomley:
       "A single fix for machines with pages > 4k (PPC mostly).
      
        There's a bug in our optimal transfer size code where we don't account
        for pages > 4k and can set the transfer size to be less than the page
        size causing nasty failures"

      Pull PCI fixlet from Bjorn Helgaas:
       "This marks the TI DRA7xx host bridge driver as broken.  Apparently it
        has never worked without some additional out-of-tree code, so I'm
        going to mark it broken now and remove it completely next cycle unless
        it's fixed"

      vmstat: allocate vmstat_wq before it is used · 751e5f5c

      kernel test robot has reported the following crash:

          ret_from_kernel_thread+0x21/0x40
      
      The reason is that start_shepherd_timer schedules the shepherd work item
      which uses vmstat_wq (vmstat_shepherd) before setup_vmstat allocates
      that workqueue so if the further initialization takes more than HZ we
      might end up scheduling on a NULL vmstat_wq.  This is really unlikely
      but not impossible.
      
      Fixes: 373ccbe5 ("mm, vmstat: allow WQ concurrency to discover memory reclaim doesn't make any progress")
