Subject: [PATCH 0/5] termios: remove arch redundancy in <asm/termbits.h>
Date:   Thu,  4 Oct 2018 15:29:48 -0700
Message-Id: <20181004222953.2229-1-hpa@zytor.com>

Precedence: bulk

<asm/termbits.h> is one of those files which define an ABI. Some were
made different due to the desire to be compatible with legacy
architectures, others were mostly direct copies of the i386
definitions, which are now in asm-generic.

This folds the IA64, MIPS, PA-RISC, and Xtensa implementations into
the generic one.  IA64 and Xtensa are identical, MIPS and PA-RISC are
trivially different and just need a handful of constants redefined.

<asm-generic/termbits.h> has a few very minor adjustments to allow this.
