From 201bdc868d9e3122bbe4491aa6b5fc4dee4cdb96 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Mon, 20 Oct 2008 17:55:29 +0000 Subject: [PATCH] powerpc: Further compile fixup for STRICT_MM_TYPECHECKS A patch of mine was recently committed to fix up STRICT_MM_TYPECHECKS behaviour on powerpc (f5ea64dcbad89875d130596df14c9b25d994a737). However, something which breaks it again seems to have slipped in afterwards. So, here's another small fix.
