* hppa-linux-tdep.c (hppa_dwarf_reg_to_regnum): Remove surrounding 

"#if 0" "#endif".  Fix mapping of DWARF DBX registers to GDB registers.
	Correct arguments and improve comments.
	(hppa_linux_init_abi): Call set_gdbarch_dwarf2_reg_to_regnum.  Delete
	disabled code.
	* hppa-tdep.c (hppa64_dwarf_reg_to_regnum): Fix check for floating
	point DBX register, change error to warning, and improve comments.
