Hello Greg,
This is habanalabs fixes pull request for 5.3-rc5. It is a bit larger than
what I would like at this stage but it contains four very important fixes
when running on s390 architecture. With these fixes the driver has been
validated as fully functional on s390 (which is BE).
In addition, it contain two more fixes for minor bugs. Specific details
of the fixes are in the attached tag.
Thanks,
Oded

habanalabs: fix device IRQ unmasking for BE host (2019-08-12 09:01:10 +0300)
----------------------------------------------------------------
This tag contains a couple of important fixes:
- Four fixes when running on s390 architecture (BE). With these fixes, the
driver is fully functional on Big-endian architectures. The fixes
include:
- Validation/Patching of user packets
- Completion queue handling
- Internal H/W queues submission
- Device IRQ unmasking operation
- Fix to double free in an error path to avoid kernel corruption
- Fix to DRAM usage accounting when a user process is terminated
forcefully.
