PATCH 1/1 x86: export 'leave_mm' symbol

This patch fixes a linking error if CONFIG_ACPI_PROCESSOR=m (this error occurs in the 'mm' branch of linux-2.6-x86.git).

We need to export the 'leave_mm' symbol so it can be accessible for the ACPI processor module.

ok - i've added this as EXPORT_SYMBOL_GPL() - this is strictly for kernel internal use.
