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. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Len Brown <len.brown@intel.com>
