Subject: [PATCH 1/5] asm-generic, termios: add alias constants from MIPS
Date: Thu, 4 Oct 2018 15:29:49 -0700 [thread overview]
Message-ID: <20181004222953.2229-2-hpa@zytor.com> (raw)
In-Reply-To: <20181004222953.2229-1-hpa@zytor.com>
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.
