I disagree quite strongly.  One major frustration for users of
non-x86 platforms is that functionality is often missing for some
time that we can make trivial to keep in sync.

I religiously watch what goes into Linus's tree for this purpose,
but that is kind of a rediculious burdon to expect every platform
maintainer to do.  It's not just system calls, we have signal handling
bug fixes, trap handling infrastructure, and now the nice generic
IRQ handling subsystem as other examples.

Simply put, if you're not watching the tree in painstaking detail
every day, you miss all of these enhancements.

The knowledge should come from the person putting the changes into
the tree, therefore it gets done once and this makes it so that
the other platform maintainers will find out about it automatically
next time they update their tree.
