acpi - Incidental MPSAFE (2)
* The changes in a639f788 revealed bubgs in acpi_thermal's support
threads. These threads start executing before the main acpi device
finishes its attach. The mplock serialization saved us before, and
removing it revealed the problem.
* Force serialization using the main acpi lock to prevent the support
threads from starting up until after the main acpi attach has
completed.
