I think <sys/select.h> is more recent, but anyway, look at the existing 
<linux/time.h> and you see why it's there.

It's fine to say it shouldn't be, but then ALL the definitions should 
move (and that should be a separate change from this patchset)... but do 
note that some of those macro definitions (which I did NOT change) are 
exported to user space so make those changes with care.
