Here's a small patch I needed to build today's kernel (well, and
yesterday's too, but I forgot).  Without looking, I'm not sure if
all the caddr_t's should be vm_offset_t's or vice versa...

Simon.

ps.  Do people want PR's for these small changes (especially when things
are in the middle of changing muchly), and are context or unidiffs the
way to go?  I prefer context myself, but whatever goes...
