* arm-linux-tdep.c (ARM_LINUX_JB_ELEMENT_SIZE): Define to 

INT_REGISTER_SIZE.
	(arm_linux_push_arguments): Use TARGET_DOUBLE_BIT instead of
	FP_REGISTER_VIRTUAL_SIZE.
	* arm-tdep.c (arm_make_sigtramp_cache): Use register_size instead
	of DEPRECATED_REGISTER_RAW_SIZE.
	(arm_register_type): Add gdbarch argument.
	(arm_register_raw_size, arm_register_virtual_size): Delete.
	(arm_register_byte, arm_extract_return_value)
	(arm_store_return_value, arm_get_longjmp_target): Update references
	to INT_REGISTER_RAW_SIZE and FP_REGISTER_RAW_SIZE.
	(arm_gdbarch_init): Likewise.  Don't set
	deprecated_register_raw_size, deprecated_register_virtual_size,
	deprecated_max_register_raw_size,
	deprecated_max_register_virtual_size, or
	deprecated_max_register_virtual_type.  Do set register_type.
	* arm-tdep.h (ARM_MAX_REGISTER_RAW_SIZE)
	(ARM_MAX_REGISTER_VIRTUAL_SIZE, INT_REGISTER_VIRTUAL_SIZE)
	(FP_REGISTER_VIRTUAL_SIZE): Delete.
	(INT_REGISTER_RAW_SIZE): Rename to INT_REGISTER_SIZE.
	(FP_REGISTER_RAW_SIZE): Rename to FP_REGISTER_SIZE.
	* arm-linux-tdep.c (ARM_NBSD_JB_ELEMENT_SIZE): Define to
	INT_REGISTER_SIZE.
	* remote-rdp.c (remote_rdp_fetch_register): Use MAX_REGISTER_SIZE.
	(remote_rdp_store_register): Likewise.
