Hello Heiko!
Thank you for patch review!

Agree.

7 - yes
10 - not
11 - yes

To make 7 more readable. Overwise patch messed up and unreadable.
It’s hard to track what going on in the patch.

I'll merge all of them.

P.S.
here comment from another thead about the patches.

So I update comments for patches.

Looks, like I study archeology with my patches, as all new ARM chips not
affected by the problem anymore.

Alexander.
