Merge tag 'misc-habanalabs-next-2019-07-04' of git://people.freedesktop.org/~gabbayo/linux into char-misc-next

Oded writes:

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
