Subject: [git pull] habanalabs pull request for kernel 5.5

Hello Greg,

This is the pull request for habanalabs driver for kernel 5.5.

It mainly contains improvements to MMU and reset code, and exposes more
information through our INFO IOCTL.

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

Thanks,
Oded

  habanalabs: add more protection of device during reset (2019-11-21 11:35:47 +0200)

----------------------------------------------------------------
This tag contains the following changes for kernel 5.5:

- MMU code improvements that includes:
  - Distinguish between "normal" unmapping and unmapping that is done as
    part of the tear-down of a user process. This improves performance of
    unmapping during reset of the device.
  - Add future ASIC support in generic MMU code.

- Improve device reset code by adding more protection around accessing the
  device during the reset process.

- Add new H/W queue type for future ASIC support

- Add more information to be retrieved by users through INFO IOCTL:
  - clock rate
  - board name
  - reset counters

- Small bug fixes and minor improvements to code.
