Yes, the case is not so many. At the beginning, I also thought this could
require incredible change. But after trying, just found it is not so bad. I have
a couple of patches to fix the remaing warnings which adds 'inline' or '_init'
markers for related functions.

I promise that all warnings get fixed with new version. And since I only have
coressponding setup to fully test x86 and ARM platform, I think we could make
this new option depend on x86 or arm temparaly so untested platforms will
not complain anymore.

Linus, is this good for you? Thank you for revewing.
