[Oded Gabbay]

Hello Greg,

This is the pull request for habanalabs driver for kernel 5.4.

It contains one major change, the creation of an additional char device
per PCI device. In addition, there are some small changes and
improvements.

Please see the tag message for details on what this pull request contains.

Thanks,
Oded

  habanalabs: correctly cast variable to __le32 (2019-09-05 14:55:28 +0300)

----------------------------------------------------------------
This tag contains the following changes for kernel 5.4:

- Create an additional char device per PCI device. The new char device
  allows any application to query the device for stats, information, idle
  state and more. This is needed to support system/monitoring
  applications, while also allowing the deep-learning application to send
  work to the ASIC through the main (original) char device.

- Fix possible kernel crash in case user supplies a smaller-than-required
  buffer to the DEBUG IOCTL.

- Expose the device to userspace only after initialization was done, to
  prevent a race between the initialization and user submitting workloads.

- Add uapi, as part of INFO IOCTL, to allow user to query the device
  utilization rate.

- Add uapi, as part of INFO IOCTL, to allow user to retrieve aggregate H/W
  events, i.e. counting H/W events from the loading of the driver.

- Register to the HWMON subsystem with the board's name, to allow the
  user to prepare a custom sensor file per board.

- Use correct macros for endian swapping.

- Improve error printing in multiple places.

- Small bug fixes.
