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
