Hello, tglx, Andy:

Could you have a review on the patches please?

They are based on 5.9-rc1 and sent when 5.9-rc1 was just settled,
and hoped to get their way into 5.10-rc1.

The first two patches can still be applied to today's tip/master,
(Sep 10 2020). The third can't, and conflicts with a commit just
added 3 days ago(#VC related). But the third removes a short snip
of code only, and is easy to be reviewed or even easy to be
applied manually. I will rebase all of them after they or the first
two are reviewed.

I'm sorry that I have to ask you to review again, because the
patches change the code you've recently changed.

Thanks
Lai
