After browsing http://lxr.free-electrons.com/source/include/linux/, I
can't find version.h file.
So I am curious about how the "<linux/version.h>" file is generated?

This is done in the top-level Makefile:
        http://lxr.free-electrons.com/source/Makefile#L997

Btw, you can try to find out something like this on your own by
grepping for 'version.h' in the kernel tree.
