From ea1eae75eb596e0628dc5e01d32c78b1f6b257fb Mon Sep 17 00:00:00 2001 From: Jeff Dike Date: Wed, 18 Jan 2006 17:42:38 -0800 Subject: [PATCH] uml: add __raw_writel definition Add implementations of the write* and __raw_write* functions. __raw_writel is needed by lib/iocopy.c, which shouldn't be used in UML, but which is unconditionally linked in anyway.
