Hello Heiko!
Thank you for patch review!

29 ????. 2016 ?., ? 18:01, Heiko St?bner [off-list ref] ???????(?):

you introduced the issue yourself in patch 11/13. In general any patch should 
never leave the kernel in a worse state than it was before, so no patch should 
ever introduce known issues itself.

Agree.

In that line of thought, don't patches 10+11 introduce warnings about unused 
functions as well when applied without patch 12?

7 - yes
10 - not
11 - yes

29 ????. 2016 ?., ? 18:03, Heiko St?bner [off-list ref] ???????(?):

Then why do you need another patch to remove them and don't do that in the 
patch removing their respective usage?

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

Maybe merge them?

I'll merge all of them.

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

3288 (and probably anything newer) is irrelevant to this discussion, as
it has the arch timer interface - that may be busted in other ways (such
as not being correctly set up by firmware and not being always-on as it
should), but frequency is not one of them. This only affects
Cortex-A9/A5 based parts.

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.

Regards,
Alexander.
