The kernel will only need modifications to sparc64, but I dont know if the utilities are using kernel includes (they shouldnt be). > 2) I add the syscall entries to include/asm-sparc64/unistd.h and > arch/sparc64/kernel/systbls.S and update NR_SYSCALLS in > arch/sparc64/kernel/entry.S and I should be done right? Check out arch/sparc64/kernel/ioctl32.c, in particular COMPATIBLE_IOCTL() and HANDLE_IOCTL(). If the ioctls have been written properly (containing u32/u64 and not unsigned long then the 32 bit and 64 bit ioctl structures will be compatible, otherwise you will need to write wrapper functions.
