Btw, looking at it, with that change every user of __put_user_size()
now passes in the properly type-cast value in 'x'.

Which means that you could remove the odd typecast in the 8-byte case:

        case 8:                                                         \
                __put_user_goto_u64((__typeof__(*ptr))(x), ptr, label); \

and make it match all the other cases:

        case 8:                                                         \
                __put_user_goto_u64(x, ptr, label);                     \

but that's just from looking at the patch, and maybe I'm missing something.
