From 22b5afce6a0f29f995b0cce83a5033892dd306d8 Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Mon, 24 Mar 2014 14:49:00 +0800 Subject: ACPICA: Add auto-serialization support for ill-behaved control methods. This change adds support to automatically mark a control method as "serialized" if the method creates any named objects. This will positively prevent the method from being entered by more than one thread and thus preventing a possible abort when an attempt is made to create an object twice. Implemented by parsing all non-serialize control methods at table load time. This feature is disabled by default and this patch also adds a new Linux kernel parameter "acpi_auto_serialize" to allow this feature to be turned on for a specific boot.
