Pull SCSI fixes from James Bottomley:
 "Nine small fixes.

  The resume fix is a cosmetic removal of a warning with an incorrect
  condition causing it to alarm people wrongly.

  The other eight patches correct a thinko in Christoph Hellwig's DMA
  conversion series. Without it all these drivers end up with 32 bit DMA
  masks meaning they bounce any page over 4GB before sending it to the
  controller.

  Nowadays, even laptops mostly have memory above 4GB, so this can lead
  to significant performance degradation with all the bouncing"

  scsi: lpfc: fix calls to dma_set_mask_and_coherent()

The change to use dma_set_mask_and_coherent() incorrectly made a second
call with the 32 bit DMA mask value when the call with the 64 bit DMA mask
value succeeded.  This resulted in NVMe/FC connections failing due to
corrupted data buffers, and various other SCSI/FCP I/O errors.

 "Six fixes, all of which appear to have user visible consequences.

  The DMA one is a regression fix from the merge window and of the
  others, four are driver specific and one specific to the target code"

We cannot wait on a completion object in the lpfc_nvme_targetport structure
in the _destroy_targetport() code path because the NVMe/fc transport will
free that structure immediately after the .targetport_delete() callback.
This results in a use-after-free, and a hang if slub_debug=FZPU is enabled.

Fix this by putting the completion on the stack.

In preparation to enabling -Wimplicit-fallthrough, mark switch cases where
we are expecting to fall through.

Notice that, in this particular case, I replaced "Drop thru" and "Fall
Thru" with "fall through" annotations, which is what GCC is expecting to
find.

Also, in some cases a dash is added as a token in order to separate the
"fall through" annotation from the rest of the comment on the same line,
which is what GCC is expecting to find.

We already need to zero out memory for dma_alloc_coherent(), as such
using dma_zalloc_coherent() is superflous. Phase it out.

This change was generated with the following Coccinelle SmPL patch:

@ replace_dma_zalloc_coherent @

-dma_zalloc_coherent(dev, size, handle, flags)

Pull SCSI updates from James Bottomley:
 "This is mostly update of the usual drivers: smarpqi, lpfc, qedi,
  megaraid_sas, libsas, zfcp, mpt3sas, hisi_sas.

  Additionally, we have a pile of annotation, unused variable and minor
  updates.

  The big API change is the updates for Christoph's DMA rework which
  include removing the DISABLE_CLUSTERING flag.

  And finally there are a couple of target tree updates"
