Oded writes:

This tag contains habanalabs driver changes for v5.17:

- Support reset-during-reset. In case the f/w notifies the driver
  that the f/w is going to reset the device, the driver should
  support that even if it is in the middle of doing another
  reset

- Support events from f/w that arrive during device resets.
  These events would be ignored which is bad as critical errors
  would not be reported and treated by the driver.

- Don't kill processes that hold the control device open during
  hard-reset of the device. The control device operations can't
  crash if done during hard-reset. And usually, only monitoring
  applications are using the control device, so killing them
  defies their purpose.

- Fix handling of hwmon nodes when working with legacy f/w

- Change the compute context pointer to be boolean. This pointer
  was abused by multiple code paths that wanted fast access to
  the compute context structure.

- Add uapi to fetch historical errors. This is necessary as errors
  sometimes result in hard-reset where the user application is
  being terminated.

- Optimize GAUDI's MMU cache invalidation.

- Add support for loading the latest f/w.

- Add uapi to fetch HBM replacement and pending rows information.

- Multiple bug fixes to the reset code.

- Multiple bug fixes for Multi-CS ioctl code.

- Multiple bug fixes for wait-for-interrupt ioctl code.

- Many small bug fixes and cleanups.
