I had since tracked that down. At least for the BSPS I've got all the files are the same in the different BSPs include/sys. I assume there are situations where they are different.

I didn't realize that, the Linux man page has "#include <sys/ioctl.h>" at the top. I'm trying to build someone else's code, I guess I've never included it myself directly, or when I did it was in the context of a make with BSP includes in scope.
