2013-02-03new helper: sigsp()Al Viro
Normal logics for altstack handling in sigframe allocation Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2013-02-03new helper: signal_setup_done()Al Viro
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 Viro
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.

2013-02-03sanitize rt_sigaction() situation a bitAl Viro
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 Nesterov
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.
