      Pull more io_uring fixes from Jens Axboe:
       "Two followup fixes. One is fixing a regression from this merge window,
        the other is two commits fixing cancelation of deferred requests.
      
        Both have gone through full testing, and both spawned a few new
        regression test additions to liburing.
      
         - Don't play games with const, properly store the output iovec and
           assign it as needed.
      
         - Deferred request cancelation fix (Pavel)"

      Pull iommu fixes from Joerg Roedel:
      
       - three Intel VT-d fixes to fix address handling on 32bit, fix a NULL
         pointer dereference bug and serialize a hardware register access as
         required by the VT-d spec.
      
       - two patches for AMD IOMMU to force AMD GPUs into translation mode
         when memory encryption is active and disallow using IOMMUv2
         functionality.  This makes the AMDGPU driver work when memory
         encryption is active.
      
       - two more fixes for AMD IOMMU to fix updating the Interrupt Remapping
         Table Entries.
      
       - MAINTAINERS file update for the Qualcom IOMMU driver.

      io_uring: fix linked deferred ->files cancellation · c127a2a1
      Pavel Begunkov authored
      While looking for ->files in ->defer_list, consider that requests there
      may actually be links.

      io_uring: fix cancel of deferred reqs with ->files · b7ddce3c
      Pavel Begunkov authored
      While trying to cancel requests with ->files, it also should look for
      requests in ->defer_list, otherwise it might end up hanging a thread.
      
      Cancel all requests in ->defer_list up to the last request there with
      matching ->files, that's needed to follow drain ordering semantics.
