Merge tag 'drm-habanalabs-next-2024-02-26' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux

 into drm-next

This tag contains habanalabs driver and accel changes for v6.9.

The notable changes are:

- New features and improvements:
  - Configure interrupt affinity according to NUMA nodes for the MSI-X interrupts that are
    assigned to the userspace application which acquires the device.
  - Move the HBM MMU page tables to reside inside the HBM to minimize latency when doing
    page-walks.
  - Improve the device reset mechanism when consecutive heartbeat failures occur (firmware
    fails to ack on heartbeat message).
  - Check also extended errors in the PCIe addr_dec interrupt information.
  - Rate limit the error messages that can be printed to dmesg log by userspace actions.

- Firmware related fixes:
  - Handle requests from firmware to reserve device memory

- Bug fixes and code cleanups:
  - constify the struct device_type usage in accel (accel_sysfs_device_minor).
  - Fix the PCI health check by reading uncached register.
  - Fix reporting of drain events.
  - Fix debugfs files permissions.
  - Fix calculation of DRAM BAR base address.
