Would we ever be setting pointers through a setparam interface? I think
making it an int makes it relatively clear that it's a 32-bit value,
though it might be valuable to use [u]intXX_t for the drm (and dri
screen private?) sruct definitions everywhere to make things clear. Also, yes, alpha, amd64, ia64, and sparc64 all have 32-bit ints and
64-bit longs and pointers.
Isn't the FB_LOCATION a pointer? :) Admittedly it will always be in the first 4GB today, but when PCI Express comes, I don't think that will always be the case. I'd hate to have to invent a new ioctl to support PCI Express when that day comes.
