Was getting the following error with allmodconfig: ERROR: "__get_user_bad" [lib/test_user_copy.ko] undefined! This was simply a missing break statement, causing an unwanted fall through. Signed-off-by: Stafford Horne <shorne@gmail.com>

2016-09-18openrisc: fix the fix of copy_from_user()Guenter Roeck
Since commit acb2505d0119 ("openrisc: fix copy_from_user()"), copy_from_user() returns the number of bytes requested, not the number of bytes not copied. Cc: Al Viro <viro@zeniv.linux.org.uk> Fixes: acb2505d0119 ("openrisc: fix copy_from_user()") Signed-off-by: Guenter Roeck <linux@roeck-us.net>

... that should zero on faults. Also remove the <censored> helpful logics wrt range truncation copied from ppc32. Where it had ever been needed only in case of copy_from_user() *and* had not been merged into the mainline until a month after the need had disappeared. A decade before openrisc went into mainline, I might add... Cc: stable@vger.kernel.org Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
