Function Documentation

int acop_handle_fault	(	struct pt_regs *	regs,
		unsigned long	address,
		unsigned long	error_code
	)

: regsiters at time of interrupt : storage address : Fault code, usually the DSISR or ESR depending on processor type

Return 0 if we are able to resolve the data storage fault that results from a CT miss in the ACOP register.
