Hello Greg,
This is the pull request for habanalabs driver for kernel 5.3.
It mostly contains improvements to the existing code base. Nothing too exciting this time.
Please see the tag message for details on what this pull request contains.
Thanks, Oded

habanalabs: Add busy engines bitmask to HW idle IOCTL (2019-07-01 13:59:45 +0000)
---------------------------------------------------------------- This tag contains the following changes for kernel 5.3:
- Change the way the device's CPU access the host memory. This allows the driver to use the kernel API of setting DMA mask in a standard way (call it once).
- Add a new debugfs entry to show the status of the internal DMA and compute engines. This is very helpful for debugging in case a command submission get stuck.
- Return to the user a mask of the internal engines indicating their busy state.
- Make sure to restore registers that can be modified by the user to their default values. Only applies to registers that are initialized by the driver.
- Elimination of redundant and dead-code.
- Support memset of the device's memory with size larger then 4GB
- Force the user to set the device to debug mode before configuring the device's coresight infrastructure
- Improve error printing in case of interrupts from the device
