Less than for all um - it's only for USER_OBJ there.  It is special,
simply because for uml the counterpart of really low-level glue has
to talk to libc.  So there we have separation into "normal kernel source"
and "userland code that uses userland headers, calls libc functions, etc."

I've dumped several header cleanup patches for uml into
git://git.kernel.org/pub/scm/linux/kernel/git/viro/um-header.git/ 
including the -idirafter, move of user_constants.h, etc.
Another fun thing: user.h used to be included directly by just about
every userland-side file.  Switched it to -include user.h (for USER_CFLAGS,
of course - not for normal stuff), killed includes, got rid of shitloads
of kern_constants.h includes at the same time.  At which point getting
rid of kern_constants.h became trivial.

Up to Jeff's approval, obviously - *including* -idirafter patch.
