LINUX KERNEL --
The latest major pull request for the Linux 4.2 kernel provides the x86 platform driver updates for this next major kernel release.

The x86 platform driver updates for Linux 4.2 have a lot of fixes, including some major clean-ups to the Toshiba drivers and refactored Bluetooth support. The new driver worth talking about is the dell-rbtn driver for a Dell airplane mode switch driver. Another interesting change is fan control support for the ASUS WMI driver.

The Dell Airplane Mode Switch driver (dell-rbtn) is an ACPI driver to allow toggling the radio controls under Linux. This device switch is sometimes called DELLABCE and DELRBTN and registers an rkfill device and receives hardware rfkill events when WiFi and Bluetooth are enabled.
