	(target_write_memory, do_xfer_memory): Ditto.
	(target_xfer_memory_partial, target_read_memory_partial): Ditto.
	(target_write_memory_partial): Ditto.
	* infptrace.c (child_xfer_memory): Ditto.
	* linux-nat.c (linux_nat_xfer_memory): Ditto.
	(linux_nat_proc_xfer_memory): Ditto.
	* dcache.c (dcache_xfer_memory): Ditto.
	* exec.c (xfer_memory): Ditto.
	* remote.c (remote_xfer_memory): Ditto.
	* remote-sim.c (gdbsim_xfer_interior_memory): Ditto.
	* target.h: Change prototypes for functions changed above.
	* linux-nat.h: Ditto.
