This patch merely flips the cmd bits.
As Andrew is doing this on amd64 (and casting to a l_XXX type), it could be that he is flipping the data into the visible range and then cutting it down to 32 bit.
I'm not familiar with the Linux DVB ioctls... is it really the case that none of the data structures have 32/64-bit architecture dependent field sizes? Great if that's the case, but if not, we need to do data structure conversions here too, as we did for V4L.
I am already in the process of discussing this with Andrew. I do not think the details are important so far for emulation@, but if someone wants to participate in the discussion...
