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.
