Chris Wilson 6a907738ab x86/asm: Enable fast 32-bit put_user_64() for copy_to_user() ... For fixed sized copies, copy_to_user() will utilize __put_user_size() fastpaths. However, it is missing the translation for 64-bit copies on x86/32. Testing on a Pinetrail Atom, the 64 bit put_user() fastpath is substantially faster than the generic copy_to_user() fallback.
