Hence, __get_user() on x86-32 with a 64-bit quantity results in __get_user_bad() being called, which is an undefined function. Only if you build with x86-64 support enabled (iow, CONFIG_X86_32 not defined) then you get the 64-bit __get_user() support. Given this, I fail to see how x86-32 can possibly work.
You're right; mea culpa. It compiles without warning on x86-32, but it does not link. I still think this is broken archtecture stupidity since put_user() works for 64 bit data types. -ben -- "Thought is the essence of where you are now."
