Just as an FYI for you guys, since we're all splashing around in busdma
code lately The things on my near-term (next several weeks) to-do
list for busdma are:
Add "small bounce" support to help reduce the bounce preallocation
overhead for handling bounces due to cacheline alignment. Almost al
Userspace buffers in load_buffer() also need temporary mappings, so it

though, so that is up to you and Michal.
Since Michal's already made the initial pa
