kernel address mapping question


From: "Chuck Tuffli" <ctuffli@xxxxxxxxx>

Is there a 1:1 mapping between physical addresses and kernel virtual
addresses? Or said a different way, can 2 kernel virtual addresses map
to the same physical address? Does the answer differ depending on
whether malloc(9) or bus_dmamem_alloc(9) are used? TIA.
