My main goal here is not to use a local timer as a global timer, but
rather to be able to support multiple local timer implementations in the
same kernel (TWD, MCT...). The "local timer on UP" is merely a consequence.

I could come up with another registration interface that fits into the
existing structure, but I thought something could be done with what we
currently have.
