This patchset adds some small enhancements, some rework and also support
for new hardware to the ioat rawdev driver. Most rework and enhancements
are largely self-explanatory from the individual patches.
The new hardware support is for the Intel(R) DSA accelerator which will be
present in future Intel processors. A description of this new hardware is
covered in [1]. Functions specific to the new hardware use the "idxd"
prefix, for consistency with the kernel driver. *** SUBJECT HERE ***
