Fix an off-by-one error in `mips_cpu_gdb_write_register' for register #72 that is handled further down in that function rather than here, matching how `mips_cpu_gdb_read_register' handles it. This register slot is a fake anyway, there's nothing in hardware that corresponds to it. Signed-off-by: Maciej W. Rozycki <macro@codesourcery.com> --- I have a further change down the queue to clean up `mips_cpu_gdb_read_register' and `mips_cpu_gdb_write_register' and make them more consistent with respect to each other as far as the handling of FP registers is concerned. For now please apply this obvious change. Thanks. Maciej qemu-mips-fpreg72.diff
