I have not yet looked at the patches, but I got a bunch of W=1 warnings 
and some sparse warnings when building your branch. Please take a look 
at these. Unfortunately the output is mixed between sparse and compiler.
The "expression using sizeof(void)" can be ignored as its a known issue
with sparse, I believe.

Thanks,
Sekhar
