Again, is 'synic' intended? Hmm, I see it throughout the patch, so it
looks intentional, but I keep trying to read it as a typo for 'sync'.
this is not a typo :)
this is an abbreviation for synthetic interrupt controller,
pls compare with this

Though there is some sense in the question itself. I think
that it would be better to keep naming it SynIC as
in the original kernel code.
