From a03fc8c375511b6ab43184ab191af3218a919646 Mon Sep 17 00:00:00 2001 From: Richard Weinberger Date: Fri, 22 Jul 2011 20:55:34 +0200 Subject: um: Make rwsem.S depend on CONFIG_RWSEM_XCHGADD_ALGORITHM rwsem.S can only be used with CONFIG_RWSEM_XCHGADD_ALGORITHM. This unbreaks the UML build on i386.
