Oded writes:

This tag contains habanalabs driver changes for v5.16:

- Add a new uAPI (under the memory ioctl) to request from the driver
  to export a DMA-BUF object that represents a memory region on
  the device's DRAM. This is needed to enable peer-to-peer over PCIe
  between habana device and an RDMA adapter (e.g. mlnx5 or efa
  rdma adapter).

- Add debugfs node to dynamically configure CS timeout. Up until now,
  it was only configurable through kernel module parameter.

- Fetch more comprehensive power information from the firmware.

- Always take timestamp when waiting for user interrupt, as the user
  needs that information to optimize the graph runtime compilation.

- Modify user interrupt to look on 64-bit user value as fence, instead
  of 32-bit.

- Bypass reset in case of repeated h/w error event after device reset.
  This is to prevent endless loop of resets to the device.

- Fix several bugs in multi CS completion code.

- Fix race condition in fd close/open.

- Update to latest firmware headers

- Add select CRC32 in kconfig

- Small fixes, cosmetics
