Is there a reason for this to be in a different patch? I mean, why don't
you squash this into the previous patch?

Actually, I guess that you could skip the spaces after the
search_dispatch_table() call (using p) and drop p1. But please test it
before doing so :)

Otherwise series looks good to me.
