SRU Justification: Impact: A type of Dell Inspiron Mini does not turn off bluetooth physically when pressing F2 (rfkill hotkey). Fix: Current kernel code expects hardware to handle the hard-rfkill switching spontaneously and only notify rfkill subsystem with the status change. This patch makes kernel to explicitly fire a SMI to switch on/off rfkill devices if BIOS reports that the hardware switch is not supported. This patch depends on the following sauce patch in lucid kernel so is not going upstream: UBUNTU: SAUCE: dell-laptop: Store the HW switch status internally rather than requerying every time Testcase: I tested the patch on a Dell Mini 10. It works smoothly.
