gdb/gdb-6.5-bz198365-IPv6.patch
Jan Kratochvil 50a6238835 - No longer disassemble invalid i386 opcodes of movQ/movA (BZ 172034). 
- Simplify the IPv6 patch for gdbserver (BZ 198365).
- Suggest fixing your target architecture for gdbserver(1) (BZ 190810).
- Fix dereferencing registers for 32bit inferiors on 64bit hosts (BZ
    181390).
- Fix `gcore' command for 32bit inferiors on 64bit hosts.
