Removing power hints for kworker threads enables easier use of workqueues in the power driver late callback. That would otherwise lead to an endless loop unless it is prevented in the power driver.
There's many kworker users; some of them actually consume lots of cputime. Therefore how did you come to the conclusion that excepting all users was the better choice of a little added complexity in the one place where it actually matters?
Agreed that it is not ideal. I will find a better solution for this problem.
can you explain which architectures we're talking about that need this? is it only old stuff, or is there anything current ?
