First (answering the other message): thanks for starting merging them!

Modules work perfectly without Modversions (and even /proc/kallsyms works 
well); with the USER_OBJS thing even modversions works perfectly, even if you 
don't like it (but I hadn't been clear about the fact the kernel runs with 
it).

If you are interested in it, I could do a trivial change (i.e. adding to each 
makefile include arch/um/Makefile.special) to avoid changing the whole 
Kbuild.

I do remember your discussion about the os- change, but it's a lot longer and 
I didn't start it. Also, I must check exactly the API to create (i.e. how to 
abstract os-specific details, which is hard since I've never programmed on 
Cygwin or Freebsd). And also, if you assume that a file handle is an integer 
(which is true only on POSIX), why do you wrap open inside os_open_file 
(which always works on POSIX)? The same question could go for other calls.
