- 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.

I pointed some folks at this and they wondered why it wasn't in the
kernel Documentation directory. So now it is.
