Subject: [git pull] habanalabs pull request for kernel 5.6

Hello Greg,

This is the pull request for habanalabs driver for kernel 5.6.

It's a small one this time and mainly contains improvements to MMU and
reset code. Hopefully I will have time to work on upstreaming the Gaudi
support code for the next kernel, but it may be postponed to 5.8.

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

In addition, I got my pgp key signed by Olof.J. I would appreciate it if
you could verify it.

Thanks,
Oded

  habanalabs: patched cb equals user cb in device memset (2020-01-27 08:23:39 +0200)

----------------------------------------------------------------
This tag contains the following changes for kernel 5.6:

- MMU code improvements that includes:
  - Flush MMU TLB cache only once, at the end of mapping/unmapping
    function, instead of flushing after mapping of every page.
  - Add future ASIC support by splitting properties of ASIC capabilities
    regarding mapping of host memory to regular and huge pages.

- Fix bug where the driver didn't halt the internal ASIC's engines before
  doing hard-reset to the ASIC

- Minimize writes to H/W during hard-reset by skipping coresight disable
  code (no point as device is going to be hard-reset).

- Fix bug where we did an extra refcnt put in the memset device memory
  function.

- Small bug fixes and minor improvements to code.
