I somewhat recant my statements below. Even in a driver that puts the full
address in the offset field, having the BO pointer may still be useful for
the purpose of adding it to a residency list somewhere.

I kind-of wonder if we want to allow for relocations and not surface state
base address in which case you'd want to do something "real" with offset.
Making this an address and then ignoring the buffer part entirely seems
like it promises a bit too much. Then again, I don't think it's really
In i965, shader programs live in a single buffer, and every batch emits
a STATE_BASE_ADDRESS packet pointing to that buffer. This takes care of
pinning the buffer for the batch; from then on, we can use an offset.
In the upcoming Iris driver, shader programs can live in multiple
buffers, and
