It feels to me like using __bitwise for access checks and then still

works, I'll be happy if we can use that.
__bitwise == "can't do anything other than bitwise operations without
an explicit force-cast". All there is to it. Hell, the very first
use had been for things like __le32 et.al., where the primitives
very much do non-bitwise accesses. They are known to be safe (==
do the same thing regardless of the host endianness). Internally
they contain force-casts, precisely so that the caller wouldn't
need to.
Thanks for clarifying that :)
