----------------------------------------------------------------
This tag contains habanalabs driver changes for v5.12:
- Add feature called "staged command submissions". In this feature,
the driver allows the user to submit multiple command submissions
that describe a single pass on the deep learning graph. The driver
tracks the completion of the entire pass by the last stage CS.
- Update code to support the latest firmware image
- Optimizations and improvements to MMU code:
- Support page size that is not power-of-2
- Make the locks scheme simpler
- mmap areas in device configuration space to userspace
- Security fixes:
- Make ETR non-secured
- Remove access to kernel memory through debug-fs interface
- Remove access through PCI bar to SyncManager register block
in Gaudi
- Many small bug fixes
