[PATCH 1/5] asm-generic, termios: add alias constants from MIPS

From: H. Peter Anvin (Intel)
Date: Thu Oct 04 2018 - 18:30:18 EST


Some architectures, in this case MIPS, need a couple of legacy alias
constants for bits. There really is no reason why we can't define them
generically for all architectures.
