- Proper ioctl() 32/64-bit binary compatibility. We need to ensure the ioctl data itself is always packed the same for 32/64-bit binaries. Additionally, the correct thing to do is encode this size in bytes as part of the command using _IOC_SIZE(). - Minor formatting changes to respect the 80 character limit. - Move all SPLAT_SUBSYSTEM_* defines in to splat-ctl.h. - Increase SPLAT_SUBSYSTEM_UNKNOWN because we were getting close to accidentally using it for a real registered subsystem.
