- The guide currently says to pad the structure to a multiple of 64-bits. This is not necessary in cases where the structure contains no 64-bit types. Clarify this concept to avoid unnecessary padding. - When using __u64 to hold user pointers, blindly trying to do a cast to a void __user * may generate a warning on 32-bit systems about a cast from an integer to a pointer of different size. There is a macro to deal with this which hides an ugly double cast. Add a reference to this macro. Signed-off-by:
