This corrects the backport of commit fe9a7082684e ("vfio/pci: Disable auto-enable of exclusive INTx IRQ"), choosing to adapt the fix to the current tree which uses an array of eventfd contexts rather than include a base patch for the conversion to xarray, which is found to be faulty in isolation.
I include the reverts here for completeness, but if the associated commits are otherwise already dropped due to previous report[1], the remainder of this series is still valid.
Largely this just adapts the mainline commits to the eventfd context array from the current internal API where they're stored in an xarray. Thanks,
Alex
