In converting __range_ok() into a static inline, I inadvertently made it more type-safe, but without considering the ordering of the relevant conversions. This leads to quite a lot of Sparse noise about the fact that we use __chk_user_ptr() after addr has already been converted from a user pointer to an unsigned long. Rather than just adding another cast for the sake of shutting Sparse up, it seems reasonable to rework the types to make logical sense (although the resulting codegen for __range_ok() remains identical). The only callers this affects directly are our compat traps where the inferred "user-pointer-ness" of a register value now warrants explicit casting.
