Hi Hans,

Sorry, somehow got that removed and I should have seen compile errors 
too but somehow did not see them. So didn't noticed that.

I see multiple patches from v11 conflict with latest linux and for 
clocks I also has to choose different id no in one of the patch.

Discussing with dmitry on his v11 feedback regarding when to allow 
freeze to happen.

So, probably will send v12 out after confirming with dmitry on having 
all feedback done now with v11.

Hopefully v12 can be the final version.
