It knows what address space it belongs to, but like I said in my mail,
it uses copyout(), which only works on "current context".

It *could* be changed to use uvm_io(), but uvm_io() requires a fair
bit of TLB frobbing and consumes KVA space, so it may be more overhead
to use uvm_io() in some situations.
