+	[BZ #23967]
+	* sysdeps/unix/sysv/linux/kernel_sigaction.h (HAS_SA_RESTORER):
+	Define if SA_RESTORER is defined.
+	(kernel_sigaction): Define sa_restorer if HAS_SA_RESTORER is defined.
+	(SET_SA_RESTORER, RESET_SA_RESTORER): Define iff the macro are not
+	already defined.
+	* sysdeps/unix/sysv/linux/m68k/kernel_sigaction.h (SA_RESTORER,
+	kernel_sigaction, SET_SA_RESTORER, RESET_SA_RESTORER): Remove
+	definitions.

+	(HAS_SA_RESTORER): Define.
+	* sysdeps/unix/sysv/linux/nios2/kernel_sigaction.h: Include generic
