* 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.
