Thanks,

  habanalabs: expose a single cs seq in staged submissions (2021-09-14 15:00:04 +0300)

----------------------------------------------------------------
This tag contains the following fixes for 5.15-rc3:

- Fix potential race when user waiting for interrupt ioctl
- Prevent possible kernel oops in staged CS ioctl
- Use direct MSI mechanism in Gaudi as a WA for a H/W issue
  regarding FLR
- Don't support collective wait ioctl operation when it
  is not supported. e.g. when the NIC ports are disabled
- Fix configuration of one of the security mechanism.
- Change error print to be rate-limited as it can be initiated
  by the user and spam the kernel log
- Fix return value of CS ioctl when doing staged CS
- Fix CS ioctl code when user doesn't supply an offset for
  the memory area that we use as fence.
- Spelling mistake fix
