From d0a9081b1e75ba62bb4450c5b8e8299a41d25278 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Fri, 20 Oct 2006 14:30:27 -0700 Subject: ACPI: uninline ACPI global locking functions - Fixes a build problem with CONFIG_M386=y (include file dependencies get messy). - Share the implementation between x86 and x86_64 - These are too big to inline anyway.
