No problem: a file inside os-* can actually *not* be a USER_OBJS.

Yes, that is true (I thought to it). However, the need to avoid code
duplication is still there.
So, avoid moving the symbols to ksyms.c, but change user_syms.c that way (i.e.
make it not be an USER_OBJ), so we can avoid duplicating code. That is
especially important because we cannot duplicate the __attribute_used__
macro, which is needed with newer Gcc, and which is defined differently for
different compilers *in kernel headers*.
If you need the rebuilt patch, just let me know and I'll post it next week
(I'm going to leave for a few days).
