cregit-Linux how code gets into the kernel

Release 4.12 include/uapi/asm-generic/termios.h


 * Most architectures have straight copies of the x86 code, with
 * varying levels of bug fixes on top. Usually it's a good idea
 * to use this generic version instead, but be careful to avoid
 * ABI changes.
 * New architectures should not provide their own version.
