The first 3 patches fix a problem with libsas handling of NCQ NON DATA commands and simplify libsas code in a couple of places. The remaining patches are fixes for the pm8001 driver: * All sparse warnings are addressed, fixing along the way many le32 handling bugs for big-endian architectures * Fix handling of NCQ NON DATA commands * Fix NCQ error recovery (abort all task execution) that was causing a crash * Simplify the code in many places With these fixes, libzbc test suite passes all test case. This test suite was used with an SMR drive for testing because it generates many NCQ NON DATA commands (for zone management commands) and also generates many NCQ command errors to check ASC/ASCQ returned by the device. With the test suite, the error recovery path was extensively exercised. Note that without these patches, libzbc test suite result in the controller hanging, or in kernel crashes.
Unfortunately I still see the hang on my arm64 system with this series :( Thanks, John
