void divide_by_zero_fault	(	size_t	vector,
		void *	param
	)

double_fault_abort()

void double_fault_abort	(	size_t	v,
		void *	p
	)

exception function – double fault abort

fpu_fault()

void fpu_fault	(	size_t	vector,
		void *	p
	)

Most important for good performance is page fault! whenever any memory related errors occurs it get fired and new page swapping process should be allocated

panic()

void panic	(	const char *	msg,
			...
	)
