+	PR 1681/cpukit
+	* shared/score/interrupt.S: With the percpu patch, ASM uses
+	INTERRUPT_STACK_HIGH instead of _CPU_Interrupt_stack_high. The
+	sparc64 was still using the old variable, which was declared in its
+	cpu.h file. This patch to comment out the declaration and switch to
+	using INTERRUPT_STACK_HIGH.
