ACPI: acpi_os_get_thread_id() returns current
Linux mutexes and the debug code that that reference acpi_os_get_thread_id() are happy with 0. But the AML mutexes in exmutex.c expect a unique non-zero number for each thread - as they track this thread_id to permit the mutex re-entrancy defined by the ACPI spec. http://bugzilla.kernel.org/show_bug.cgi?id=6687 Signed-off-by: Len Brown <len.brown@intel.com>
