void flush_icache_range	(	unsigned long	start,
		unsigned long	end
	)

flush_icache_range - Globally flush dcache and invalidate icache for region : The starting virtual address of the region. : The ending virtual address of the region.

This is used by the kernel to globally flush some code it has just written from the dcache back to RAM and then to globally invalidate the icache over that region so that that code can be run on all CPUs in the system.
