[Umesh Nerlige Ramappa]

Hi all,

This is a revival of an earlier patch series submitted by Lionel
Landwerlin - https://patchwork.freedesktop.org/series/54280/

The patches enable interrupt support for the perf OA unit in
i915, further details can be found in the orignal series linked
above.

Regards,
Umesh
