  A few new DSA operations are introduced [1]:
1. Memory fill with 16 bytes of pattern.
2. Translation fetch.
3. Data Integrity Extension (DIX) generate.

This series adds descriptor definitions for the new DSA operations.
With the definitions, user can issue the DSA operations to optimize
corresponding transactions.

Change log:
v2:
- Change anonymous struct to uint64_t for pattern_upper (Dave Jiang)
v1:
https://lore.kernel.org/dmaengine/20221108003944.2095567-1-fenghua.yu@intel.com/

Reference:
1. DSA 2.0 spec: https://software.intel.com/content/www/us/en/develop/articles/intel-data-streaming-accelerator-architecture-specification.html

    memory fill operation
  dmaengine: idxd: Add descriptor definitions for DIX generate operation
  dmaengine: idxd: Add descriptor definitions for translation fetch
    operation

Any comment on this patch set? Will you pick it up? This can be applied 
cleanly to upstream kernel.

Thank you very much!
