Hi Greg,
This is the pull request containing fixes for 5.2-rc2/3.
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
20:38:04 +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 un-initialized mutex
