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.
