Subject: [PATCH 0/2] dma-mapping: benchmark: modify the dma_map_benchmark directory

This series moves the dma_map_benchmark utility out of the selftests
directory and fixes an ABI regression introduced in an earlier change.
No functional behaviour of the benchmark itself is changed.

Qinxin Xia (2):
  tools/dma: move dma_map_benchmark from selftests to tools/dma
  dma-mapping: benchmark: Add padding to ensure uABI remained consistent
