Do you mean pmap_enter()?  That's concerned with physically mapping in a
page at the request of the VM system.  Unless you're planning on having
hardware assistance for your magic, that's not where you want to be. 
pmap_enter takes a paddr_t because that's (roughly) what the machine's VM
hardware uses.  Unless you plan on having some seriously funky hardware
assistance for your project, you don't want to be messing with
pmap_enter().

I suspect what you actually want is somewhere in sys/uvm/uvm_pager.c, but I
don't know that area very well.

You are, at least, berking up the wrong tree.
