openrisc: signal: Fix sparse address space warnings
The __user annotations in signal.c were mostly missing. The missing annotations caused the warnings listed below. This patch fixes them up by adding the __user annotations. arch/openrisc/kernel/signal.c:71:38: warning: incorrect type in initializer (different address spaces) arch/openrisc/kernel/signal.c:71:38: expected struct rt_sigframe *frame arch/openrisc/kernel/signal.c:71:38: got struct rt_sigframe [noderef] __user * arch/openrisc/kernel/signal.c:82:14: warning: incorrect type in argument 1 (different address spaces) arch/openrisc/kernel/signal.c:82:14: expected void const volatile [noderef] __user * arch/openrisc/kernel/signal.c:82:14: got struct rt_sigframe *frame arch/openrisc/kernel/signal.c:84:37: warning: incorrect type in argument 2 (different address spaces) arch/openrisc/kernel/signal.c:84:37: expected void const [noderef] __user *from arch/openrisc/kernel/signal.c:84:37: got struct sigset_t * arch/openrisc/kernel/signal.c:89:39: warning: incorrect type in argument 2 (different address spaces) arch/openrisc/kernel/signal.c:89:39: expected struct sigcontext [noderef] __user *sc arch/openrisc/kernel/signal.c:89:39: got struct sigcontext * arch/openrisc/kernel/signal.c:92:31: warning: incorrect type in argument 1 (different address spaces) arch/openrisc/kernel/signal.c:92:31: expected struct sigaltstack const [noderef] [usertype] __user * arch/openrisc/kernel/signal.c:92:31: got struct sigaltstack * arch/openrisc/kernel/signal.c:158:15: warning: incorrect type in assignment (different address spaces) arch/openrisc/kernel/signal.c:158:15: expected struct rt_sigframe *frame arch/openrisc/kernel/signal.c:158:15: got void [noderef] __user * arch/openrisc/kernel/signal.c:160:14: warning: incorrect type in argument 1 (different address spaces) arch/openrisc/kernel/signal.c:160:14: expected void const volatile [noderef] __user * arch/openrisc/kernel/signal.c:160:14: got struct rt_sigframe *frame arch/openrisc/kernel/signal.c:165:46: warning: incorrect type in argument 1 (different address spaces) arch/openrisc/kernel/signal.c:165:46: expected struct siginfo [noderef] [usertype] __user *to arch/openrisc/kernel/signal.c:165:46: got struct siginfo * arch/openrisc/kernel/signal.c:170:33: warning: incorrect type in argument 1 (different address spaces) arch/openrisc/kernel/signal.c:170:33: expected struct sigaltstack [noderef] [usertype] __user * arch/openrisc/kernel/signal.c:170:33: got struct sigaltstack * arch/openrisc/kernel/signal.c:171:40: warning: incorrect type in argument 2 (different address spaces) arch/openrisc/kernel/signal.c:171:40: expected struct sigcontext [noderef] __user *sc arch/openrisc/kernel/signal.c:171:40: got struct sigcontext * arch/openrisc/kernel/signal.c:173:32: warning: incorrect type in argument 1 (different address spaces) arch/openrisc/kernel/signal.c:173:32: expected void [noderef] __user *to arch/openrisc/kernel/signal.c:173:32: got struct sigset_t * Signed-off-by:Stafford Horne <shorne@gmail.com> Reviewed-by:
