Changelog v6

• Drop supports_veventq viommu op
• Split bug/cosmetics fixes out of the series
• Drop the blocking mutex around copy_to_user()
• Add veventq_depth in uAPI to limit vEVENTQ size
• Revise the documentation for a clear description
• Fix sparse warnings in arm_vmaster_report_event()
• Rework iommufd_viommu_get_vdev_id() to return -ENOENT v.s. 0
• Allow Abort/Bypass STEs to allocate vEVENTQ and set STE.MEV for DoS mitigations

I rebased a v7 on rc2, but found no changelog at all from v6 to v7, except Bagas's "Reviewed-by".

So, I think we can still review on this version?

Thanks Nicolin
