2009-12-16Toshiba Bluetooth Enabling driver (RFKill handler v3)Jes Sorensen
This patch adds support for the ACPI events generated by the RFKill switch on modern Toshiba laptops, and re-enables the Bluetooth USB device when the switch is flipped back to the 'on' position.

2009-12-16gru: send cross partition interrupts using the gruJack Steiner
GRU Message queue instructions are used to deliver messages to other SSIs within the numalink domain. In most cases, a single GRU mesq instruction will deliver both the message AND an interrupt to notify the other SSI that a messsage is present. In some cases, however, the interrupt must be sent explicitly. To improve resilency, the GRU driver should send these explicit interrupts using the GRU to write the remote chipset register. Current code sends the interrupt using a cpu instruction to write the chipset register.
