From eeee7853c4ffaf5b9eb58f39708e3c78f66cee15 Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Thu, 2 Apr 2009 12:31:16 +0900 Subject: sh: Add a command line option for disabling I/O trapping. This adds a 'noiotrap' kernel command line option to permit disabling of I/O trapping. This is mostly useful for running on emulators where the physical device limitations are not an issue.
