From 63b852a6b67d0820d388b0ecd0da83ccb4048b8d Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 13 May 2009 22:56:24 +0000 Subject: asm-generic: rename termios.h, signal.h and mman.h The existing asm-generic versions are incomplete and included by some architectures. New architectures should be able to use a generic version, so rename the existing files and change all users, which lets us add the new files.
