…inux-platform-drivers-x86 Pull x86 platform-driver updates from Darren Hart: "New model support added for Dell, Ideapad, Acer, Asus, Thinkpad, and GPD laptops. Improvements to the common intel-vbtn driver, including tablet mode, rotate, and front button support. Intel CPU support added for Cannonlake and platform support for Dollar Cove power button. Overhaul of the mellanox platform driver, creating a new platform/mellanox directory for the newly multi-architecture regmap interface. Significant Intel PMC update with CannonLake support, Coffeelake update, CPUID enumeration, module support, new read64 API, refactoring and cleanups. Revert the apple-gmux iGP IO lock, addressing reported issues with non-binary drivers, leaving Nvidia binary driver users to comment out conflicting code.
