x86: x86 core dump TLS This makes ELF core dumps of 32-bit processes include a new note type NT_386_TLS (0x200) giving the contents of the TLS slots in struct user_desc format. This lets post mortem examination figure out what the segment registers mean like the debugger does with get_thread_area on a live process.
