Constify a number of static structs that are never modified to allow the
compiler to put them in read-only memory. In order to do this, constify a
number of local variables and pointers in structs.

This is most important for structs that contain function pointers, and
the patches for those structs are placed first in the series.

Thanks so much for the contribuition. You only need to refine the PATCH 
2 a little bit and re-send it.

Thanks for reviewing. Just to clarify, did you mean patch 7 (since
that's the one you commented on)? And is it enough to send just that
patch or do you want the entire series resent?

Hi Rikard,  no worries then. I have already corrected them and queue 
them in the gvt-next branch, you can double check them if you like. They 
are going through a QA test cycle first and later start their journey to 
the upstream. All good. :) Thanks so much for the contribution again.

Zhi.
