-config SIG_HUP
-	int "SIGHUP"
-	default 1
-	---help---
-		The SIGHUP would be sent to programs when the serial line was dropped,
-		often because the connected user terminated the connection by hanging up
-		the modem. The system would detect the line was dropped via the lost
-		Data Carrier Detect (DCD) signal.
-
-config SIG_INT
-	int "SIGINT"
-	default 2
-	---help---
-		The SIGINT signal is sent to cause a task termination event.
-		SIGINT may be ignored or caught by the receiving task.
-
-config SIG_QUIT
-	int "SIGQUIT"
-	default 3
-	---help---
-		Similar to SIGINT, but controlled by the QUIT character (usually Ctrl+\).
-		When a process exits due to a SIGQUIT will generate a core file when it exits,
-		in the sense that it is similar to a program error signal.
-
-
-config SIG_ILL
-	int "SIGILL"
-	default 4
-	---help---
-		The SIGILL executed an illegal instruction. It is usually because of an
-		error in the executable file itself or an attempt to execute a data segment.
-		This signal may also be generated when the stack overflows.
-
-config SIG_TRAP
-	int "SIGTRAP"
-	default 5
-	---help---
-		Trace trap signal, generated by a breakpoint or other trap instruction.
-		Used by debugger.
-
-config SIG_ABRT
-	int "SIGABRT"
-	default 6
-	---help---
-		The SIGABRT signal is sent to a process to tell it to abort, i.e. to
-		terminate. The signal is usually initiated by the process itself when
-		it calls abort function of the C Standard Library, but it can be sent
-		to the process from outside like any other signal.
-
-config SIG_BUS
-	int "SIGBUS"
-	default 7
-	---help---
-		Signal generated by system bus error, illegal address, including memory
-		address alignment (alignment) error. eg: Accessing an integer four words long,
-		but its address is not a multiple of 4.
-
-config SIG_FPE
-	int "SIGFPE"
-	default 8
-	---help---
-		Issued in case of a fatal arithmetic error. This includes not only
-		floating point errors, but also overflow and all other arithmetic errors such
-		as division by zero.
-
-config SIG_KILL
-	int "SIGKILL"
-	default 9
-	---help---
-		A signal that can terminate any process and can only be sent by the administrator;
-		the signal will not be captured and ignored.
-
-config SIG_USR1
-	int "SIGUSR1"
-	default 10
-	---help---
-		Value of standard user signal 1 (SIGUSR1). Default: 10
-
-config SIG_SEGV
-	int "SIGSEGV"
-	default 11
-	---help---
-		Illegal use of memory address signal by attempting to access memory that is not
-		allocated to you, or attempting to write to a memory address that does not have
-		write permission.
-
-config SIG_USR2
-	int "SIGUSR2"
-	default 12
-	---help---
-		Value of standard user signal 2 (SIGUSR2). Default: 12
-
-config SIG_PIPE
-	int "SIGPIPE"
-	default 13
-	---help---
-		The SIGPIPE signal is sent to a task termination event.
-		This signal is generated when write on a pipe with no one to read it.
-		SIGPIPE may be ignored.
-
-config SIG_ALRM
-	int "SIGALRM"
-	default 14
-	---help---
-		Default the signal number used with POSIX timers (SIGALRM).
-		Default: 14
-
-config SIG_TERM
-	int "SIGTERM"
-	default 15
-	---help---
-		The SIGINT signal is sent to cause a task termination event.
-		SIGTERM may be ignored or caught by the receiving task.
-
-config SIG_CHLD
-	int "SIGCHLD"
-	default 17
-	depends on SCHED_HAVE_PARENT
-	---help---
-		The SIGCHLD signal is sent to the parent of a child process when it
-		exits, is interrupted (stopped), or resumes after being interrupted.
-
-config SIG_CONT
-	int "SIGCONT"
-	default 18
-	---help---
-		Resume a suspended/paused task.  SIGSTOP only has an action when
-		send to a stopped task.  SIGCONT is ignored by other task.  SIGCONT
-		may not be caught or ignored by a stopped task.
-
-config SIG_STOP
-	int "SIGSTOP"
-	default 19
-	---help---
-		Enable the default action for SIGSTOP and SIGTSTP (suspend the
-		task) and SIGCONT (resume the task).
-
-config SIG_TSTP
-	int "SIGTSTP"
-	default 20
-	---help---
-		Suspend pause a task.  Unlike SIGSTOP, this signal can be caught or
-		ignored.
-
-config SIG_TTIN
-	int "SIGTTIN"
-	default 21
-	---help---
-		A process cannot read from the user’s terminal while it is running as a
-		background job. When any process in a background job tries to read from
-		the terminal, all of the processes in the job are sent a SIGTTIN signal.
-		The default action for this signal is to stop the process. For more
-		information about how this interacts with the terminal driver, see Access
-		to the Controlling Terminal.
-
-config SIG_TTOU
-	int "SIGTTOU"
-	default 22
-	---help---
-		Similar to SIGTTIN, the signal generated by the interrupt driver when a
-		background job wants to read data from the user terminal. The signal does
-		not occur and a read error occurs when the process reading the data blocks
-		or ignores the signal, or when the process group in which the data is being
-		read is an isolated process group. errno is set to ETO. The only difference
-		is that the process can choose to write in the background.

-	---help---
-		An emergency situation on the socket is the message sent.
-

-config SIG_VTALRM
-	int "SIGVTALRM"
-	default 26
-	---help---
-		Virtual clock signal. Similar to SIGALRM, but calculates the CPU time
-		occupied by the process.
-
-config SIG_PROF
-	int "SIGPROF"
-	default 27
-	---help---
-		Similar to SIGALRM/SIGVTALRM, but includes the CPU time used by the process
-		and the time of system calls.
-
-config SIG_POLL
-	int "SIGPOLL"
-	default 29
-	depends on FS_AIO
