From a1b200e27c0426ea98c1231a2b78c6094eb073e4 Mon Sep 17 00:00:00 2001 From: Heiko Carstens Date: Mon, 9 Aug 2010 17:18:28 -0700 Subject: mm: provide init_mm mm_context initializer Provide an INIT_MM_CONTEXT intializer macro which can be used to statically initialize mm_struct:mm_context of init_mm. This way we can get rid of code which will do the initialization at run time (on s390). In addition the current code can be found at a place where it is not expected. So let's have a common initializer which architectures can use if needed. This is based on a patch from Suzuki Poulose.
