The pointer in get_user() and friends is supposed to be a __user pointer. But in SH's implementation of __get_user_check(), the pointer is assigned to a local variable __gu_addr which is lacking the __user annotation. As consequence, a warning is issued for every of its uses.
So, add the missing __user annotation (this remove ~700 warnings when using defconfig).
