From 9c8d6381dc107dbc2bfdbfdcaefe0d42e5b5b362 Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Wed, 14 Nov 2007 17:00:31 -0800 Subject: [PATCH] uml: fix build for !CONFIG_PRINTK Handle the case of CONFIG_PRINTK being disabled. This requires a do-nothing stub to be present in arch/um/include/user.h so that we don't get references to printk from libc code.
