Yes, it seems like overkill.

How about something like adding PARAVIRT_LAZY_FLUSH as an argument to
set_lazy_mode?  It would be valid to use at any time, and it would flush
any pending work while still remaining in whatever lazy mode its
currently in.  That way kmap_atomic can flush anything pending without
having to muck around with the current lazy state.
