2013-02-03sparc: switch to use of generic old sigactionAl Viro6-69/+13
note that due to historical accident we do *not* directly take generic versions - need to check and invert the sign of signal number first. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2013-02-03sparc: switch sys_compat_rt_sigaction() to COMPAT_SYSCALL_DEFINEAl Viro2-17/+8
note that while struct compat_sigaction is the generic one, syscall itself *isn't* - different arguments. IOW, CONFIG_ODD_RT_SIGACTION stays. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2013-02-03new helper: signal_setup_done()Al Viro2-0/+10
usual "call force_sigsegv or signal_delivered" logics. Takes ksignal instead of separate siginfo/k_sigaction. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2013-02-03new helper: get_signal()Al Viro1-0/+18
On success get_signal_to_deliver() fills k_sigaction and siginfo. _All_ users pass it addresses of the local variables sitting in the same function. Then they proceed to pass those addresses pretty much in tandem to a bunch of helper functions; again, all callers of those helpers are passing them such a pair, and one that had been through get_signal_to_deliver() at that. The obvious cleanup: introduce a new type that would contain a <k_sigaction,siginfo> pair (struct ksignal) and begin switching to using it. Turns out that it's convenient to store the signal number in the same object. New helper, taking that sucker is a wrapper for get_signal_to_deliver(); takes struct ksignal * and returns bool. On success fills ksignal with the information for signal handler to be invoked. For now it's a macro (to avoid header ordering headache), but eventually it'll be a function in kernel/signal.c, with get_signal_to_deliver() folded into it.

Switch from __ARCH_WANT_SYS_RT_SIGACTION to opposite (!CONFIG_ODD_RT_SIGACTION); the only two architectures that need it are alpha and sparc. The reason for use of CONFIG_... instead of __ARCH_... is that it's needed only kernel-side and doing it that way avoids a mess with include order on many architectures.

2013-01-20ia64: kill thread_matches(), unexport ptrace_check_attach()Oleg Nesterov3-29/+1
The ia64 function "thread_matches()" has no users since commit e868a55c2a8c ("[IA64] remove find_thread_for_addr()"). Remove it. This allows us to make ptrace_check_attach() static to kernel/ptrace.c, which is good since we'll need to change the semantics of it and fix up all the callers.

The tty is NULL when the port is hanging up. chase_port() needs to check for this. This patch is intended for stable series. The behavior was observed and tested in Linux 3.2 and 3.7.1.

2013-01-17staging/sb105x: PARPORT config is not good enough must use PARPORT_PCSteven Rostedt1-1/+1
The sb105x driver calls parport_pc_probe_port() which isn't defined if PARPORT_PC isn't enabled. Protecting it with CONFIG_PARPORT is not good enough, must protect it with CONFIG_PARPORT_PC.

2013-01-178250/16?50: Add support for Broadcom TruManage redirected serial portStephen Hurd4-1/+52
Add support for the UART device present in Broadcom TruManage capable NetXtreme chips (ie: 5761m 5762, and 5725). This implementation has a hidden transmit FIFO, so running in single-byte interrupt mode results in too many interrupts. The UART_CAP_HFIFO capability was added to track this. It continues to reload the THR as long as the THRE and TSRE bits are set in the LSR up to a specified limit (1024 is used here).

2013-01-17pty: return EINVAL for TIOCGPTN for BSD ptysJiri Slaby1-0/+2
Commit bbb63c514a3464342967237a51a21ea8f61ab951 (drivers:tty:fix up ENOIOCTLCMD error handling) changed the default return value from tty ioctl to be ENOTTY and not EINVAL. This is appropriate. But in case of TIOCGPTN for the old BSD ptys glibc started failing because it expects EINVAL to be returned. Only then it continues to obtain the pts name the other way around. So fix this case by explicit return of EINVAL in this case.
