Subject: [PATCH 3/3] UML - Add __raw_writel definition
Date: Sun, 15 Jan 2006 01:33:36 -0500 [thread overview]
Message-ID: <200601150633.k0F6Xa2I015470@ccure.user-mode-linux.org> (raw)
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.
