For some unexplicable reason that means it is almost impossible to see 
the actual problems in most CI dmesg logs because they are swamped with 
irrelevant display messages that cannot be filtered out. For example, I 
recently manually grep'd out all the display spam from a bug report log. 
The dmesg file went from 12MB to 700KB. That is a significant problem 
that makes bug triage way harder than it needs to be.

Meaning just repost patch #1 only and expand to more intel_gt_* files? 
Sure, if someone will actually reply to that patch with some kind of r-b 
first so I know I'm not still wasting my time on a huge re-write that 
will to be redone multiple times when someone objects to the use of a 
colon or the lack of spaces, braces or whatever.
