Userspace uses long in quite a few places more than the kernel. Which gives me neat proof that I'm the only guy on this side of the galaxy who ever tried to run glxgears on a 64bit machine with sis graphics on linux. Note that the longs in drm_sis_mem_t aren't aligned properly, so this won't even work with 32bit userspace on 64bit kernel as-is. Hence the patch can't break that, either. Nope, I'm not nuts enough to write the 32bit ioctl compat layer for this and test it with some wine app. Even though hunting the ebay dungeons for a sis card actually supported by the mesa drivers casts some doubts on this ...
