[PATCH] x86_64 linkage error on UP_IOAPIC

ChangeSet 1.1517, 2005/05/13 10:19:23-03:00, [email protected]

	[PATCH] x86_64 linkage error on UP_IOAPIC
	
	When 2.4.31-pre2 is configured for X86_64 && !SMP && UP_IOAPIC
	it fails to link:
	
	arch/x86_64/kernel/kernel.o(.text+0x4591): In function `enable_irq':
	: undefined reference to `send_IPI_self'
	make: *** [vmlinux] Error 1
	
	A broken change in 2.4.31-pre{1,2} made the UP kernel reference
	a symbol which is only defined in the SMP kernel.
	
	The patch below fixes this by reverting that change.
