Thanks for your contribution; you need to add a `Signed-off-by' tag though for your change to go anywhere. Also I think the <asm/uaccess.h> part will need some further work; at the very least the comment needs to be updated to state why the conditional has now been hardwired. Ultimately I think all the hackery can go and `__copy_tofrom_user_nocheck' and `__clear_user' be replaced with direct calls to `__copy_user' and `__do_clear_user' respectively (and `__do_clear_user' renamed to `__clear_user' at the same time) as the +/- 4MiB branch range is too low these days to guarantee a kernel binary to fit within. Alternatively a configuration option might be added for the branch optimisation to stay instead if selected, perhaps also adding the `-msmall-text' compiler option to let small configurations take advantage of it globally rather than just in <asm/uaccess.h>. This might not be liked by people running build bots though as it would inevitably cause some configurations to fail linking.
