With the introduction of _OSI("Windows 2012") = true in Linux kernel, BIOS
changes its behaviours for wireless hotkey. As a result, the original
implementation in hp-wmi no longer works.
BIOS declares a new ACPI device for the wireless hotkey and a new kernel
module is created to handle its event generated by pressing the hotkey.
The patches are included in upstream and are cherry-picked from Linus's repo.
