This series for Engine reset functionality from Gen8 onwards. Some of the
prep patches are already sent and merged, now follows more of them and
implementation patches.
Many many thanks to Mika and Chris for their time in review, these patches
have become much more simpler than they were originally and they are easy
to follow as well. I request you to please review further and provide
feedback so that they can be get closer to upstream. We can also get some
testing done now.
Tomas Elf originally started upstreaming effort for Gen8 and I am
continuing it, any mistakes they are mine.
These are based on nightly tree pulled on 11th April.
