What exactly: that the logic is copied or how that code (>> & ~ + & ~)
looks like?
If the former, I already thought of making a couple internal defs to
avoid copying.
If the latter, I also thought of this, just wanted to be clear that it's
the same as in xp_raw_get_dma(). But it can be refactored to look more
fancy anyway.
Or the compound return looks ugly? Or the struct initialization?
Thanks,
