Hi Greg,

This is the pull request containing fixes for 5.2-rc2/3. It is now
correctly rebased on your char-misc-linux branch.

It supersedes the pull request from 12/5, so you can discard that pull
request, as I see you didn't merge it anyway.

It contains 3 fixes and 1 change to a new IOCTL that was introduced to
kernel 5.2 in the previous pull requests.

See the tag comment for more details.

Thanks,
Oded

  habanalabs: Avoid using a non-initialized MMU cache mutex (2019-05-24 22:46:15 +0300)

----------------------------------------------------------------
This tag contains the following fixes:

- Halt debug engines when user process closes the FD. We can't allow the
  device to issue transactions for a user which doesn't exists anymore.

- Fix various security holes in debugfs API.

- Add a new opcode to the DEBUG IOCTL API. The opcode is designed
  for setting the device into and out of debug mode. Although not a fix
  per-se, because this is a new IOCTL which is upstreamed in kernel 5.2, I
  think this is justified at this point because we won't be able to change
  the API later.

- Fix a bug where the code used an uninitialized mutex
